For the problem:
A) how many degrees of freedom does the system
have?
B) sketch a free-body diagram for each rigid body in the
system.
C) Write Newton’s second law of moments for each rigid
body.
D) List the unknowns, and compare to the number of
equations. If necessary specify any kinematic constraints that are
required to provide enough equations to determine the
unknowns.
