The uniform slender bar AB has length L = 1.45 ft and weight WAB= 20 lb. Rollers D and E, which are pinned at A and B, respectively, can be modeled as two identical uniform disks, each with radius r = 1.5 in: and weight Wr = 0.35 lb. Rollers D and E roll without slip on the surface of a cylindrical bowl with center at O and radius R = 1 ft. Determine the system’s kinetic energy when G (the center of mass of bar AB) moves with a speed v = 7 ft/s.
