Required information A tower crane is lifting a 13,000-lb object B at a constant rate of 7 ft/s while rotating at a constant rate of = 0.15 rad/s. B is also moving outward with a radial velocity of 1.5 ft/s. Assume that object B does not swing relative to the crane (i.e., it always hangs vertically) and that the crane is fixed to the ground at O. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. 42 ft 16 ft 3ġ 16 ft 25 ft B Determine the radial velocity required of the 20 ton counterweight A to prevent the horizontal motion of the system's center of mass. (Round the final answer to four decimal places.) The radial velocity required is 1.5 ft/s.
