Problem 1. (10 pts) Consider a pulley that is well-approximated as a vertical disc of radius R = 0.125 m and mass M = 4.1 kg that can rotate about an axis through its center. A massless, inextensible string is hung over the pulley and two small masses mı = 0.15 kg and m2 = 0.20 kg are hung, one on each end of the string. They are released and the pulley begins to rotate as the small masses accelerate,...
In the pulley system shown in Figure P2.33, assume that the cable is massless and inextensible, and assume that the pulley masses are negligible. The force f is a known function of time. Derive the system's equation of motion in terms of the displacement. For the system shown in Figure P2.34, the solid cylinder of inertia I and mass m rolls without slipping. Neglect the pulley mass and obtain the equation of motion in terms of x.
