Determine the distance the piston or pulley at C must move to the left in order to lift the load a distance h . The cable is attached at B , passes over the pulley at C , then D , E , F , and again around E , and is attached at G . Given: h 2f t = Solution: Δ s F h = L 2 s C 2 s F + = Δ s C 2 Δ s F Δ s Δ s F Δ s C 2ft = Problem 12-195

Unformatted text preview: A is controlled by a motor at B such that when the collar is at s A , it is moving upwards at v A and slowing down at a A . Determine the velocity and acceleration of the cable as it is drawn into the motor B at this instant. Given: d 4 ft = s A 3 ft = v A 2 − ft s = a A 1 ft s 2 = Solution: L s A 2 d 2 + s B + = Guesses v B 1 ft s = a B 1 ft s 2 = 134...
