Problem 5 - Rigid Body Kinetics (25 pts) The sheave of 400-mm radius has a mass of 50 kg and a radius of gyration of 300 mm. The heave and its 100-kg load are suspended by the cable and the spring, which has a stiffness of 1500 N/m. If the system is released from rest with the spring initially stretched 100 mm, determine the velocity of O after it has dropped 50 mm. 400 mm 100 kg

Problem 3 (25 pts) 01 The disk of mass m and radius R is rolling without slipping with angular speed W1 = 1 g/R on the horizontal surface when it encounters a step of height R/4. Assuming that the disk does not rebound when it hits the step and that it rotates about it, determine (a) the normal force between the disk and the corner immediately after the impact, R/4 (b) the percentage of energy lost during the impact, (c)...
