Question details

Problem 2.15 The disk shown in Figure P2.15 has a radius R of 0.25m, a mass M of 10kg, and an inertia Ip of 0.4kg*m2 about its center. The free length L of the spring is 1m and its stiffness k is 25N/m. The disk is released from the rest in the position shown and rolls without slipping Assume DI-2.25m and D2-2m (a) Express the total energy of the system in terms of x. (b) Calculate the angular velocity when the disks center is directly below point o D2
