System of Forces

A force is an external influence or agent that changes the state of a system. According to Newton's second law, the force applied to a body is proportional to the change in momentum of a body. Hence, whenever a force is applied to a body, its momentum changes. If the body is at rest, under the action of force, its state of rest changes to motion. In other words, the magnitude of the momentum of the body changes from zero to a measurable value. Similarly, if the body possesses some initial velocity, it has some associated momentum, the effect of force can cause the body to halt or come to rest, that is, the momentum reduces to zero.

A ball of 1lb is sliding around in a circular path with a speed as shown. If the attached wire is pulled down through the hole with a constant speed of 1.5ft/s, 1) determine the ball's speed at the instant when r=1.5ft; 2) the work done by the wire; 3) time required for the ball to get there. Neglect friction and the size of the ball. 11b B=3 ft (VB)₁ = 6 ft/s v,=1.5ft/s
Question: A 200block is suspended from an inextensible cable which is wrapped around a drum of 1.3-ft radius rigidly attached to a flywheel. The drum and flywheel have a combined centroidal moment of lc = 10 lb-ft-s ^ 2 .At the instant shown, the velocity of the block is 5 ft/s directed downward. Knowing that the bearing at A is poorly lubricated and that the bearing friction is equivalent to a couple M of magnitude 60 lb-ft, determine the velocity of the block after it has moved 4.2 ft downward (in ft/s).
