Answers Test 2, 2001-2002

You may have a different number of equations depending.

Problem 1:
I had 4 unknowns and 4 equations (AM rate, 2 kinematics equations and a geometry equation)

Problem 2:
I had 5 equations and 5 unknowns (2 LM rate equations, 1 AM rate equation, 2 geometry equations.  I treated the systems as two bars (with their own center of gravities).

Problem 3
I'm sorry, but I didn't have an electronic version of this problem.
