Engineering Mechanics - Dynamics Chapter 19 Solution: F Δ tM v = F th 7 5 Mr 2 Δω = vr = Thus h 7 5 2 = h 7 5 r = *Problem 19-32 The double pulley consists of two wheels which are attached to one another and turn at the same rate. The pulley has a mass M C and a radius of gyration k O . If the block at A has a mass M A and the container at B has a mass M B , including its contents, determine the speed of the container at time t after it is released from rest. Given: M C 15 kg = k O 110 mm = M A 40 kg = r 1 200 mm = M B 85 kg = r 2 75 mm = t 3s = Solution: Guess v A 1 m s = v B 1 m s = ω 1 rad s = Given M A gtr 1 M B 2 M A v A r 1 M B v B r 2 + M C k O 2 + = v A r 1 = v B r 2 = v A v B
