2. The weight of the disk is 30 lb and its radius of gyration equals 0.6 ft. The spring has a stiffness of 2 lb/ft and an unstretched length of 1 ft. Find the velocity of the center G at the instant G moves 3 ft to the left. Assume that the disk is released from rest in the position shown and rolls without slipping. k=2 lb/ft

2.b. The 12-lb lever OA with 10-in radius of gyration about O is initially at rest in the vertical position (0-90°). At this position, the attached spring of stiffness 3 lb/in is stretched by 4 in. Calculate the constant moment M applied to the lever through its shaft at O which will give the lever an angular velocity o4 rad/sec as the lever reaches the position 0 k3 Ib/in. 30° MWWN 0 15" 15

A 520 lb uniform disk with center G and radius
r = 3 ft is connected by a pulley system to a
counterweight A weighing 75 lb. The system is initially at
rest when A is allowed to drop, thus causing the disk to
roll without slipping to the right. Neglect the inertia of pulley
B and the cord, but model pulley C as a uniform
disk with radius rC = 0.8 ft and weight
