A 2.5-lb collar is attached to a spring and slides without friction along a circular rod in a vertical plane. The spring has an undeformed length of 4 in and a constant k = 20 lb/ft. Knowing that the collar is at rest at C and is given a slight push to get it moving, determine (a) the velocity of the collar as it passes through point A, and (b) the force exerted by the rod on the collar as...
A 5 kg collar is attached to a spring and it slides along a smooth bar. The spring has undeformed length of 35 cm and a constant k= 700 N/m. The collar is released from rest as shown below. Determine the force exerted by the rod on the collar when; a) The collar is at point A b) The collar is at point B. Not that both A and B are on the curved portion of the rod. A 5...
