Three bars, each 2 ft long and weighing 9.66 lb, are pinned together to form the equilateral frame shown in Fig. P-1245. They rotate in a horizontal plane about a vertical axis at A. What torque is required to cause an angular acceleration of 12 rad per sec? What is the reaction at A when the frame reaches a speed of 38.2 rpm?
