5a. 5b. Draw free body diagrams and write equations of motion for x and 0 in the following pulley system. Note that the pulley has both rotational damping and rotational inertia, and note that x > 0 for displacement of the mass toward the pulley. damping C rotational J f(t) R Xxx k m Combine the two equations from part (a) into a single governing equation for x. First reduce to one equation by solving for and eliminating the cable tension force. Then eliminate 0 using x = re. Simplify the resulting equation, moving all x terms to the left-hand side.
