A mass of 2 kg is attached to the spring, and the motion takes place in a viscous fluid that offers a resistance numerically equal to the magnitude of the instantaneous velocity. If the system is driven by an external force of (15 cos 3t - 10 sin 3t) N, determine the steady state response. Express your answer in the form R cos(wt 8).

- An open belt drive connects two pulleys 1.2 m and 0.5 m diameter on parallel shafts 3.6 m apart. The belt has a mass of 1kg/m length and the maximum tension in it is not to exceed 2kN. The 1.2 m pulley, which is the driver, runs at 200 rpm. Due to the belt slip on one of the pulleys, the velocity of the driven shaft is only 450 rpm. If the coefficient of friction between the belt and pulley is 0.3, find: 1. Torque on each of the two shafts, 2.
