Question

A 256-lb block is released from rest when the spring is unstretched. The drum has a weight of 76 lb and a radius of gyration of k_O = 0.9 ft about its center of mass O. The coefficient of stiffness of the spring is k=78 lb/ft. The radius of the drum are: r_in=0.485ft and r_out=0.82ft.

Find the velocity of the block after it has descended d=4 feet.

A 256-b block is released from rest when the spring is unstretched. The drum has a
weight of 76 Ib and a radius of gyration of ko - 0.9 ft about its center of mass O.
The coefficient of stiffness of the spring is k-78 Ib/ft. The radius of the drum are:
f-0.485ft and ra-O.82t.
The velocity of the block after it has descended d-4 feet. Give your answer with 1
decimal.
