Draw apparatus here
ABSTRACT
(Here you need to describe the objective – analyzing a machine for efficiency and
mechanical advantage – in a couple of concise sentences. A person reading the abstract
should know immediately what you did and found out.
PROCEDURE
Describe in a readable paragraph how you set up the experiment. Draw a
picture/diagram of your apparatus.
OBSERVATION AND CALCULATIONS
This is where you include chart of the observations you made. Name and number the
chart. For analyzing input and output in a machine it could look like this:

IMA
efficiency
DISCUSSION
Write a paragraph about what you learned about pulley systems, and how they might be
useful in various human activities. Include some speculation about why the efficiency
was not 100%. (Where was energy/work lost in the operation of the pulley?
SOURCES OF ERROR
Make comments about the difficulties and possible errors, imprecision, inaccuracies that
might have affected your work, and how the setup might be improved. Make sure you
mention the efficiency, and how that might be improved.
CONCLUSION
Say something about how the equations held up in a real machine.
ACKNOWLEDGEMENTS
Put here a short sentence thanking your lab partners by name (or a polite wish that they
are able to more fully engage in their next lab!)
