Team Constitution
Preamble:
We the kids of Bartlett Academy have created this lawful constitution to guide us throughout
our experience in designing a Can Crusher. We will follow each and every rule, and will make
sure that these rules are followed. As a group we will become one, and respect one another as
so.
Amendment 1- Work and Responsibility
- Do not procrastinate
- Do your own work
-Do your work on time
- Complete all your duties in a professional manner
-Do not rely on someone to do your work
Amendment2- Group Guideline
-Respect all your members
-Respect all their ideas
-Do not let past issues effect this project
-Do not goof off
-Issues will be dealt as a group
-Do not let the group down
Amendment3- Workshop Rules
-Follow the normal workshop rules
-Do not goof off while working
-When cutting, gluing, or sanding, do it in a neat and clean manner
-Let each and every individual gets hand on in this project
Conclusion:
We will follow these rules with much discipline, and will prove that 4 different
individuals can work together and be successful. This constitution will guide us in becoming
stronger, smarter, and responsible.

Problem Statement
We work for Alpha Engineering Company. A customer of our company, Roadrunner Trucking,
has received a notice signifying that the total volume of the aluminum cans the company
disposes must be reduced by 70%. If this is not done, Roadrunner Trucking will have to pay a
$ .05 penalty per can. As a result, they have contacted your firm about developing a solution that
will reduce the volume of their aluminum cans.
Background/Justification
This could be a potential dilemma in the real world. Many companies may be dissatisfied if they
have to pay extra money when they can do something to prevent it.
Customers
Roadrunner Trucking
Mr.Pritchard- ITC Teacher
Scope
Materials:
Screws
Nails
Metal hinges
PVC
Wood
Metal brackets
The following expertise will be used to create the Can Crusher…
Mahematics- Ms. Hernacki
Biology- Ms. Byerly
IED- Mr. Hund
ITC- Mr. Pritchard
The specific customer constraints are…
The max space the design can occupy is 18”x24”x30”.
Materials that can be used are wood, pvc, metal brackets, metal hinges, screws and nails.
Use a minimum of one simple machine.
It is permissible to place the aluminum can in the crusher. A 5% bonus will be awarded if a
self- loading system is developed. (Note: Self-loading means that the aluminum can goes into
the crusher without any human intervention).
The aluminum can must fall into the aluminum can bin once it is crushed. No human
intervention is to be involved.
The aluminum can bin must slide in and out of the crusher.
The aluminum can bin must be sized to hold 20 crushed cans.
All parts of the can crusher must be fabricated.
The design is to be one unit.
Must be manually operated.
Deliverables
All of the work related to creating the design will be documented in the technical report. We will
also be presenting a PowerPoint presentation to the class. The final product and our technical
report will go to Mr. Pritchard, our ITC teacher.
Brainstorming
What is a Can Crusher?
What are Can Crushers used for?
How are they used?
How are they used in the real world?
How man aluminum cans can be crushed at one time?
What simple machines are we going to use in our design?
How big will the hole where the cans fall be?
How do we create a self-loading system?
What was the first can crusher?
Research & Generate Ideas
A can crusher is an instrument used for crushing aluminum soda cans. This is done to
make storage easier. While most recycling companies do not require you to crush can’s, it is a
good idea to crush them so that your recycling bin does not fill up fast. The can crusher crushes
the cans so that they are flat. This provides more space in the bin. The very first can crusher was
the human foot. People found aluminum cans on the ground and they would stomp on them to
flatten them. This stomping often led to foot injuries so entrepreneurs came up with the idea of
developing alternatives that could be used by hand. These can crushers are used in the real world
when people or companies that have aluminum cans want to save space in the recycling bin. To
do this, they invest in a can crusher. The amount of aluminum cans that can be crushed at once
depends on the type of can crusher. Some can crushers only crush one can at a time; others are
able to crush multiple cans. The most common simple machine used to design and create can
crushers is the lever. The lever is used to pull down the top of the crusher which puts force on the
can and therefore, crushes it. The hole where the cans fall out should be smaller than the
uncrushed can and bigger than the crushed can. We can create a self-loading system by using a
robot to aid the cans into the can crusher.
A can is 4.8 inches in length and 2/5 in diameter with a volume of 23.562
The volume of 30% of a can is 7.0686
A can crusher works by using a force to compress the aluminum
A lever changes one direction of force into another crushing a can easier
Materials: wood, pvc, metal brackets, metal hinges, screws, and nails
The bin must be 141.372 inch3
An automatic loading system must be able to conserve space and hold 20 full sixed cans in a way
that they can drop without getting stuck
