Review Part A Each of the 9-1b spheres is rigidly attached to the crossbar frame as shown in (Figure 1). The frame has a negligible weight and is free to rotate. If a couple moment M = (5t + 2) 1b . ft, where t is in seconds, is applied to the frame, determine the speed of each of the spheres in 4 s, starting from rest. Express your answer to three significant figures and include the appropriate units. UA ? ft V = 32.2 S Figure Submit Previous Answers Request Answer I Review V PartA The rod of negligible mass is subjected to a couple moment of M = (30t2) N - m and the engine of the car supplies a traction force of F = (15t) N to the wheels, Where t is in seconds.
