             1 LABORATORY EXERCISES
2.1 Description of Labs

            There will be four labs and one computer simulation in the fall semester. These labs will be
       performed independent from class time. You will work in groups of your choice that are not larger
       than four members. The data collection aspect of these labs must be performed during the 2-hour lab
       period offered Monday to Thursday after school. Analyses can effected in any location of
       convenience to you and your lab group. Below will be deadlines for the submission of the formal
       report for each lab experience. Remember you are required to submit TWO copies of your
       papers. One will be returned and the other kept on file. In addition, you must supply a single sheet of
       paper detailing the efforts of each person in the group and it must include the signatures of all
       members.
            Due to bandwidth restrictions and formatting dramas, no electronic submissions will be
       accepted. I realize .pdf format resists this, but I think proper that you effect the printing for
       these reports instead of me.
            Late submissions are NOT acceptable without proof of insurmountable difficulties for all 4
       members of the group. Prevent this by having the report stored on more than one computer or on a
       web page and prepared a few days in advance.
            The details will of the experiments and the project will be made clear when this document is
       released to the class on the first day of school. Full use of your graphing calculator, Maple, Excel and
       possibly some programming will be necessary to complete some of the analysis required for these
       labs. Here is your chance to be a scientist!
            You are expected to design the procedures and analysis for each experiment. You will be marked
       on how well you first conform to the requirements of form and the basic academic constraints of the
       experiment and then on how you handle the more subtle and technical aspects. This is a measure of
       your scientific acumen and creativity. Yes, you can do more, but does it really contribute to the
       experiment? You need to weigh all of this very carefully. You will not have time to waste in your
       laboratory experience in university (or professional life) so find ways to check that you are on the
       right track before you waste a lot of time.

       2.4 Marking Rubric

            On the next page is a copy of the rubric that will be used to grade your formal lab reports.
       Comments from Mr. van Bemmel will be copiously written on the report and a short discussion will
       be had with each group when the report is returned. This may have to happen outside of class
       depending on our schedule. Students who wish further input should make an appointment with Mr.
       van Bemmel at a time of mutual convenience.
            Although Mr. van Bemmel will guide you and answer specific questions related to form and
       other aspects of a paper, he will not “go over the report” prior to handing it in. You get one chance
       for your mark. You are expected to read EVERY WORD of the lab manual and the course profile
       that pertain to submission format and use it properly.

       2.4.1 Lab Notebooks

           You must submit your lab notebook along with your formal report. One Notebook per
       report please.

    SPECIAL NOTE:

     I have spent some time investigating an interesting and useful experiment to perform in the Interference
and Quantum Mechanics sections of our course. As of this writing, this is a work in progress. I have decided
that this experiment will NOT be assigned this year.

EXPERIMENT 1 – MECHANICS

    SOUP CAN ROLL
                           You must use two cans of soup. One is a consommé and the other is a
                       cream soup. The cans must have the same-labelled mass and have the same
                       dimensions at least to eye. It is better if the soups chosen do not have chunks
                       of material in them.
                           These cans are to be rolled down two ramps and then on to a flat surface.
                       The slope must be otherwise smooth and so must be the floor. One slope is to
                       be slight permitting the consommé can to roll further. The other must be
                       much steeper and result in the cream soup rolling further. You may have to
     BASIC             cover the slopes with some material to prevent the can from slipping. You
     REQUIREMENT       may also modify the floor ramp interface to allow the can to smoothly
                       transfer from the ramp to the floor without appreciable bouncing. (If you
                       think this matters)
                           In either case, one soup can will roll further than the other. Why? I want a
                       complete analysis of the energy that is imparted to these cans and where it
                       goes. What is going on inside the cans? What is the reason for the variation or
                       lack thereof in the results from the two ramps? Justify your theory with some
                       intelligent analyses. Full uncertainty analysis is expected. Innovative
                       techniques to obtain better results are of interest.
                           Your report will follow all the constraints given in the course package.
     ESSENTIAL         However, it will also conform to the page limit set forth below. Using
                       appropriate and reasoned analysis your report must answer the question as
     REPORT            why one can rolled further (in both experiments) and discuss using
     INFORMATION       mathematical models the probable situation inside the cans during both
                       experiments as can be inferenced by motion of same.

  EXPERIMENT 1A – MECHANICS

  COLLISION SIMULATION
               You will write a simulation using code in C, C# or C++ that will simulate a two dimensional collision.
               This code will first verify itself solving a 2D collision that is first head on with a motionless target, then a
             glancing collision with a motionless target. The verification is taken from a photocopy of a worked problem
             or an example from a text book that will show conclusively that your program is producing comparable
             results
               The program will then analyze the situation where the target is moving.
               This is a challenging problem algebraically, but it can be done using a simulation. It is a problem that you
BASIC        can intrinsically understand and thus find the benefit of producing a simulation for these types of problems.
             The real problem you will face here is how to model the actual events around the collision itself. We know
REQUIRE-     that the materials compress for very short time span and spring back. Assume for this experiment that your
MENTS        collisions are elastic.
               Since our laboratory equipment is limited in this area, you will use a stress ball, map out its compressive
             properties, and use these in your simulation.

               BONUS: You may choose to include the rotation of the objects either as an initial condition and/or because
             of their impact for a maximum 20% bonus, but it must be done properly and with sound reasoning and most
             importantly as a simulation not a rendering. For clarity consider my primer on Simulations which can be
             found on my web page www.hmvb.org


                Submission format: Your submission must include.

                1. A complete listing of your code including reasonable documentation
ESSENTIAL       2. Print outs of the Excel plots of the solutions generated by your program.
                3. Photocopies of the sample problems you have used to verify the operation and accuracy of your
REPORT
             program.
INFORMA-        4. Photocopy of a 2D glancing collision with a moving target
TION            5. No marks or consideration given for any GUI work regardless of the quality
                6. A block diagram (Flow chart) of what your program is doing to produce the data.
                7. Analysis of the stress ball spring constant experiment including any uncertainties. Is it linear etc? Is k a
             value or function?


PAGE LIMIT      Not enforced


                Only equipment found in the school lab or reasonable contents of a student’s pencil case are permitted.
EQUIPMENT    Experiment data must be collected at the school using the aforementioned equipment unless express
RES-         permission to the contrary has been secured. Analyses can be performed in any location.
TRICTIONS       Translation. The analysis of the stress ball must be done at school in our lab. The rest can be done at your
             convenience, but the program must be transportable to school and runable there.

    EXPERIMENT 2 – SHM

    SIMPLE PENDULUM
                              You are to investigate the effects that bob mass and the length of a
       BASIC
                         pendulum have on its period. This is to be done at various release angles and
       REQUIREMENT       the effect the release angle has on the pendulum’s period must be modelled.
                              The differential equation for the motion of the pendulum must be derived
                         and the constants measured. For small values of theta, the DE can be
                         simplified using the small angle equation. You must, however, be prepared to
                         defend what range you consider a small angle and how this estimation affects
                         the overall precision of your work. You are also expected to empirically
       ESSENTIAL         model the effects of large values of theta on the period. Thus your final
       REPORT            expression will be something like Period(theta, Length) = Ideal
       INFORMATION       Period(length) + Period Perturbation (theta, length). CAUTION: Observe that
                         the square root of small g is essentially equal to Pi. Do not ignore this!
                              You are also expected to let your pendulum swing for an extended period
                         to determine the damping coefficient involved. You should predict what
                         value for this coefficient is expected due in part to air resistance and compare

EXPERIMENT 3 – ELECTRICITY

DC CIRCUIT ANALYSIS
AC INTRODUCTION
                        You will construct two separate circuits and analyze each of them as
                     required below.

                         Circuit 1: Resistor network – Connect a bridge resistor network and
                     then predict using KCL and KVL the voltages and currents of each segment.
                     Then measure the same and verify these values. Account for any
                     discrepancies. Full use of uncertainty analysis is required. Caution: It helps to
                     choose resistors that have prime numbers or your linear system can be more
                     easily dependant making the theoretical solution harder to find. Also, do not
                     select resistors for the different branches of your circuit that differ by more
                     than 1 order of magnitude as this will make your uncertainty analysis
                     difficult.
                         Circuit 2: RC Circuit. You will construct a RC circuit and then observe
                     the charging and discharging curves. You will have to choose values for R
                     and C that can be read with the typical operational window of the I-books.
   BASIC
                     These can be determined by appropriate attention to the theory of this type of
   REQUIREMENT       electrical circuit.
                         HINT: In addition, the capacitor when nearing full charge will behave
                     like a very large resistance. These phenomena will cause your voltmeter to
                     give erroneous reading when in parallel to the capacitor. Part of your
                     methodology will be to devise a work around to this issue and explain it in
                     your paper
                         Circuit 3: Oscilloscope Familiarization You will connect the
                     oscilloscope to the AC signal generator and obtain a waveform. From this
                     you will measure the wave characteristics on the screen of the scope. The
                     frequency counter can then be used to verify the frequency. You are expected
                     to image the waveform from the screen of the scope. The TI-8x’s, I-books are
                     not permitted on this segment as you are expected to learn the use and
                     operation of an oscilloscope. You must use the analog scopes for this
                     exercise. The digital scope is NOT to be used for this segment unless express
                     permission from your instructor is given.

                         Your report will follow all the constraints given in the course package.
                     However, it will conform to the page limit set forth below. The resistance of
   ESSENTIAL         the CBL will begin to affect the readings you get from the voltage probe. You
                     will have to sort this out.
   REPORT                You are expected to discuss the symmetry or lack thereof of the RC
   INFORMATION       profiles.
                         Your report must indicate if your research confirms or challenges the
                     accepted situation.
                         4 pages + 1 page indicating the duties performed by each member. Please
   PAGE LIMIT        print your work on BOTH sides of the paper.
                         You may use digital and / or analog voltmeters. You may also use I-books
   EQUIPMENT
                     / TI8x / CBL voltmeters if you wish and the equipment is available. You must
   RESTRICTIONS      use Kirchoff’s work to solve these circuits. Thevenin and Norton

                               equivalents are not permitted in this analysis. You may however, show
                               how these theorems conform to the work you have done, but your analysis
                               cannot be justified exclusively by Norton or Thevenin Theorems.

      Note: There is only ONE unique solution to the KVL circuit in part 1. You have to be sure that the
equations you choose are not linearly dependant. This can be checked when you set up your matrix by taking
the determinant.

EXPERIMENT 4 – ELECTROMAGNETISM
AC CIRCUIT ANALYSIS
                            Circuit 1: RC Phase shifting You will reconstruct the series RC circuit that
                        was used during experiment #3. Measure whatever parameters you deem necessary
                        with whatever equipment the school can provide to measure the reactance of the
                        capacitor and the phase shift it generates between the current and the voltage
                        waveforms. Research the topic of Lissajous figures and measure them for this
                        circuit. Does the data from this observation compare well with other data collected
                        above. What is the common use of this technique? Choose your R and C values
                        carefully to encourage a sensible phase shift of current and voltage (You are
                        permitted to alter the parameters of both R, C and f to obtain a reasonable Lissajous
                        Figure. However, you are still expected to show what the phase shift would have
                        been with the components from your Lab 3 experiment. If the phase shift of these is
                        acceptable then fine otherwise predict and show that it is small and then choose new
                        components to complete this part of the experiment). Your theoretical knowledge
                        should guide you here. The values of these components have to be carefully
                        chosen to permit impedance matching. You should research this before
                        entering the lab. The results of this computation should also be included in your
                        analysis.

                            Circuit 2: CLR Circuit. Now connect a CLR circuit with components whose
                        impedance with match the output of the function generator and predict the natural
                        frequency of this circuit. (Show the reasoning here in your report please.) Make a
BASIC REQUIREMENTS      plot of frequency amplitude v. frequency and see if your resonance point is in fact
                        the natural frequency. Some analysis of your curve should be effected to obtain the
                        mathematically sound maxima here.

                            Circuit 3: Transformer Using the coils and magnetic cores provided by           the
                        school make a rudimentary transformer. Starting with a low frequency of 20          Hz
                        increase the frequency of the input voltage until the output voltage drops          off
                        considerably. It should be much higher. Why does this happen? Where does all        the
                        energy go?

                           Circuit 4: Solenoid Using the hall effect probe and DC power source of a low
                        enough voltage to keep the current in the coil at a safe level (ie. 1.5 V) measure the
                        B field inside the solenoid and also along it longitudinal axis. Compare the values
                        you obtained with those predicted by the theory describing your circuit. Consider
                        using the Helmholtz coils for this

                            Extension: Energize a second solenoid whose B field is similar, but not
                        necessarily exactly the same as the first one. Place the second solenoid proximate to
                        the first one at an arbitrary angle well of the axis. Compute the theoretical B field in
                        R3 as it is distorted by the two solenoids. NOTE: Proper solutions to this
                        challenging aspect can earn up to 110% on this paper. However, papers that do
                        not meaningfully undertake this aspect will not receive a grade in excess of
                        90%.

                                       The directional ability of the Hall effect probe is a problem. This is exacerbated

      REPORT INFORMATION           problem. To complete the extension described above you would have to carefully
                                   locate the probe’s tip around the solenoid in 3D. This apparatus would be your own
                                   design. (Course work primarily deals with the fields along the longitudinal axis of

                   You are required to construct a device that conforms to the following.

                   Using mechanical and electronic means, subject to the restrictions in this
                assignment construct a device that can obtain the value of the local magnetic field in 3
                dimensions. The project will be marked for its ability to accomplish this task and the
                accuracy obtained. The display should be a digital readout and not a simple
                mechanical gauge. This display should have three significant digits. A selector can be
BASIC           used to obtain the readings for each cardinal direction, permitting the construction of a
REQUIREMENTS    single LED type display. The cycling of the display through the 3 axes can also be
                automated electrically if you prefer.
                   The unit would be required to produce an accurate result within 5 seconds of a
                change of the B field.
                   Originality is stressed in the design of this project. If your work is found to
                conform in a major way to an existing design you marks for this aspect will not be as
                impressive.


                    Engineers design things and technicians build them. Therefore, it will be your
                 burden to design your project prior to constructing it. Your group will be held
                 accountable for not only the quality and originality of your design, but also for how
                 well it conforms to your final project. Your outline will contain the following
                 aspects

                    1.    A description of the design of the device with explanations of why this
                          design is optimal and conforms to the laws of physics etc. A proper
                          blueprint type diagram showing the mechanical dimensions and structure of
                          the device. You must give details of where you sourced your ideas. I will
                          check this. I expect some creativity and originality here not a simple copy
PROSPECTUS
                          of an Internet project.
                    2.    A wiring diagram of the device using established techniques and symbols
DUE 01 DEC 06
                    3.    An overall set of procedures to construct and test this device. Tolerances

                          and expected performances during construction should be included.
                    4.    A production schedule and a system to monitor same that can be produced
                          upon demand.
                    5.    A budget whose total cannot exceed $150 CDN (Fair market value charged
                          for any gifts of material).
                    6.    A pamphlet created in a quasi-professional manner that would accompany
                          this project that would be used for marketing purposes. Do be careful about
                          the claims you make, you will be held accountable!

                    You must cite any sources that you have consulted where the design of this
                 device is not your own. Failing to do so will result in forfeit of the grade for that
                 design.

                        The electronic aspect restricts you only in the prohibition of interfacing with a
                     computer, using microcontrollers and other small computers. Your display device
                     MUST be of your own design/construction. Hooking it up to a simple voltmeter
                     would be an unsatisfactory choice. This would also apply to buying some type of
                     device box that connects to a computer. You are expected to do this the hard way.
                        You are NOT permitted to use weight sensing devices such as load cells or
                     piezoelectric devices. Nor are strain gauges permitted.
                        You may NOT construct your own power supply for this unit. Any aspects
EQUIPMENT
                     of this project that use voltages greater than 12V must be CSA approved.
RESTRICTIONS
                        You have a budget of $150.00 CDN total for this project This includes any
                     “donations”. The limit is “fair market value” for the items you use in your project

                       You are strongly discouraged from attempting to use the school shops to
                     build this device.

                        They are understaffed and your safety is an insurmountable issue. The
                     construction of this device will largely have to occur outside of the building. If you
                     have intractable problems with this aspect come and see me.
                        If you are unsure about the legality of a given part ASK ME FIRST.

                             FORMAL REPORT MARKING RUBRIC – PROJECT
       ASPECT                                          DESCRIPTION                                          MARKS
                         If the device works DURING the demo you will get full marks here. If you
                     can document (i.e. video or some other evidence) that it did work, but
                     something bad happened on demonstration day then you will earn at least 8
  PERFORMANCE        marks. Beyond that, it will be the teacher’s judgement as to how close you were          /10
                     to getting it operational. By working the device should at least give readings that
                     are in the same direction as the (in)decrease of the load and proportional to the
                     stimulus
                         If you have begun your data display system, but it is not operational, you
                     cannot earn more than 3 marks here. If you have not begun constructing this and
                     have only the design then you will receive zero for this section.
      DEVICE
     ACCURACY
                         For the rest of the marks you system would have to have some form of                 /10
                     calibration in that when it displays some level this has physical meaning and
                     that you have modelled and can be used to infer the mass. Hex/Octal readouts
                     are allowed, but will not receive the highest marks.

                        Specifically how well did the finished device correspond to that specified in
 CONFORMITY OF
  PROSPECTUS
                     the prospectus? This goes right down to dimensions and electronic part                   /20
                     specifications etc.
                        1. All form rules enforced here (Operating Manual format)
      FORM OF
     PROSPECTUS
                        2. Is the production schedule reasonable?                                            /10
                        3. Did this group produce an up to date production status when asked?
                        1. How professional is the Operating Manual?
 FORM – FINAL           2. How professional is the Marketing Pamphlet?
DOCUMENTATION           3. How complete is the testing and how well is this information presented?           /20
                        4. How accurate is the budget and did it fall under the limit?

                        1.    Was the device constructed to perform for some time or is it some kind
     QUALITY OF               of lash up?
 CONSTRUCTION           2. Was there effort dedicated to make the device appealing, NOT                      /10
                              necessarily by coloration,. But in the quality of its manufacture etc.
                        How original was your design. How properly did it use the available laws of
      DESIGN
                     physics to effect its aim. How efficient is this unit supposed to be?                   /20
                         Utterly superb projects may receive grades in excess of 100%, but only when the
                     resulting performance greatly exceeds the above standards. No mark will exceed 110%.
  TOTAL GRADE        You are reminded that this is an AP part of the course and any marks here will be             %
                     adjusted.


     This project will reward planning and originality along with performance. It is a challenge and I suggest
that you get right at it.

     Good luck!
