If the frame is subjected to a couple M = at 2 + b , and the cylinder is subjected to force F , which is always directed as shown, determine the speed of the cylinder when t = t 1 . The cylinder has a speed v 0 when t = 0. Given: m C 10 kg = t 1 2s = a 8N m s 2 = v 0 2 m s = d 0.75 m = b 5Nm = e 4 = F 60 N = f 3 = Solution: m C v 0 d 0 t 1 t at 2 b + d + f e 2 f 2 + Fdt 1 + m C v 1 d = v 1 v 0 1 m C d 0 t 1 t at 2 b + d f e 2 f 2 + Fdt 1 +

If the rope is pulled inward with a constant speed v r , determine the speed of the box at the instant r = r B . How much work is done after pulling in the rope from A to B ? Neglect friction and the size of the box. Given: W 8 lb = r A 2 ft = 371...
