Engineering Mechanics - Dynamics Chapter 13 Problem 13-10 The elevator E has a mass M E and the counterweight at A has a mass M A . If the elevator attains a speed v after it rises a distance h , determine the constant force developed in the cable at B . Neglect the mass of the pulleys and cable. Units Used: kN 10 3 N = Given: M E 500 kg = M A 150 kg = v 10 m s = h 40 m = Solution: Guesses T 1kN = F = a 1 m s 2 = Given TM A g M A a = FT + M E g M E a = v 2 2 ah = F T a Find
