Use energy method(Chapter 18)to solve the following problems
Problem 1: A motor delivers 50lb*ft of torque to the pinion gear D, which is in mesh with the larger gear A and the attached drum over which the cable winds. If A has a weight of 120lb and a radius of gyration k_(A)=0.6 ft, determine the velocity of the 50 -lb crate C when it has risen 5ft starting from rest. Neglect the mass of the pinion gear and the cable and pulley at B.
