A 0.6-lb collar A is released from rest, slides down a frictionless rod, and strikes a 1.8-lb collar B which is at rest and supported by a spring of constant 34
A 0.5-kg block B slides without friction inside a slot cut in arm OA which rotates in a vertical plane at a constant rate= 2 rad/s.
A 0.7-lb block rests on top of a 0.5-lb block supported by but not attached to a spring of constant 9 lb/ft. The upper block is suddenly removed.
A 1-kg collar C slides without friction along the rod OA and is attached to rod BC by a frictionless pin. The rods rotate in the horizontal plane
A 0.9-kg block B is connected by a cord to a 2.4-kg block A which is suspended as shown from two springs, each of constant 180 k = N/m, and a dashpot of damping
A 1.4-kg block is supported as shown by a spring of constant k = 400 N/m which can act in tension or compression.
