Engineering Mechanics - Dynamics Chapter 13 The safe S has weight W s and is supported by the rope and pulley arrangement shown. If the end of the rope is given to a boy B of weight W b , determine his acceleration if in the confusion he doesn’t let go of the rope. Neglect the mass of the pulleys and rope. Given: W s 200 lb = W b 90 lb = g 32.2 ft s 2 = Solution: L 2 s s s b + = Initial guesses: a b 1 ft s 2 = a s 1 ft s 2 = T 1lb = Given 02 a s a b + = 2 TW s W s g a s = b W b g a b = a b a s T
