Objectives: The objectives of the course are to teach you the fundamentals of mechanical systems, and
methods for identifying, formulating and solving analysis and design problems involving mechanical
systems. The term mechanical system refers to mechanisms, gears, and cams.

Catalog description: Design and kinematic analysis of mechanisms, gear trains, planetary gear trains, cam-
and-follower devices with applications to mechanical systems.

Course outcomes: After completing the course you should be able to:

    a) Understand the basic concepts of mechanical systems including mechanisms. [a]

       satisfies Grashof’s condition. [a]
    c) Perform position analysis of simple mechanisms, including a four-bar linkage and a slider-crank
       mechanism using graphical methods or algebraic methods. Understand the pros and cons of each
       method. [a]

       program to perform this task. [a]

       law of gearing and why a gear with involute tooth profile form satisfies this law. [a]
    n) Be able to find the points of initial and final contact of mating teeth in a gear set. Compute the
       paths of approach and recess. [a]
    o) Learn about gear standards. [a]
    p) Be able to design the profile of a gear tooth. [c]
    q) Understand when to use planetary gears and be able to perform velocity analysis of these gears. [a]
    r) Solve problems using complex numbers and trigonometry [a]
    s) Complete a design project [c]

Assessment Tools: Exams, homework assignments and design projects.
Overview: The course consists of two parts. In the first part, we will study displacement, velocity and
acceleration analysis. We will learn how to determine the displacement, velocity and acceleration of the
components of mechanical systems for which the input displacement, velocity and acceleration are given.
We will develop computational tools for this purpose. Concepts and methods will be demonstrated on
linkages. In the first part, we will also learn how to design mechanisms to produce a desired output motion.
In the second part, we will apply what we learnt in the first part on cams and gears.

Prerequisite: MIME-2300, Engineering Dynamics, Prerequisites by topic: Kinematics of particles and rigid
bodies, Newton's laws, energy methods. Vectors, differential and integral calculus and complex numbers.

Exams, homework and grading: There will 2 midterm and a final exams. There will about eleven
homework assignments and two design projects. You must submit homework assignments in class on the
due date. No late homeworks will be accepted. Your grade will be based on the following: Homework
(20%), Midterm exams (25% each), Final (30%)

Your grade will be determined based on the following scale:
                   Overall score                                          Letter grade
                      90-100                                                 A or A-
                     80-89.99                                             B or B+ or B-
                     70-79.99                                             C or C+ or C-
                     60-69.99                                             D or D+ or D-

Missed homework or exams: If you are unable to submit a homework or take an exam because of a genuine
emergency (such as illness, jury duty, funeral) then you should contact me by E-mail or in person and
provide written documentation as soon as possible. Submit your assignment as soon as possible. In case
you have to miss an exam I will decide if I will give you a make-up test or adjust the weight of the final
exam or other homework assignments. If you fail to provide proper written documentation of the
emergency you will get a zero for the assignments, or exams you missed. Note that going on vacation is
not considered an emergency.

Academic dishonesty: Students may discuss and exchange ideas about homework assignments and
projects but they are expected to submit their own work. No collaboration is permitted in exams. Trying to
get credit for someone else’s work or deprive another student from getting credit for his/her own work will
be considered academic dishonesty. If a student observes such an incident, the student must report it to the
professor. The incident will be investigated. Penalties include, but are not limited to, getting an F for an
assignment or an exam, getting an F for the class or dismissal from the College of Engineering or the
Cellular phone policy in class: Use of cellular phones during class distracts students. Therefore, cell
phones must be switched-off during class.
Class attendance: Students are expected to attend all class sessions. If you have a genuine emergency that
prevents you from attending a class, you should contact me by Email preferably before the class. You will
still be responsible for getting the information you missed.
Class sessions: Each class will start with a 5-10 minute review of the previous class. Then we cover new
material and close with an overview of what we covered. I typically ask a lot of questions during class to
make sure you understand the material and wait until somebody answers. I encourage you to try to answer
the questions. Please do not hesitate to ask questions.
Computer usage: Some homework problems can be solved efficiently using computer. You can use any
software program you like including FORTRAN, MATLAB, Excel, or MathCad.
Email and Web page: Homework assignments, design problems, solutions, review sessions, and exam
prospectuses will be posted on the course web page or/and will be emailed electronically.
