The shaft, lever, and handle are welded together and constitute a single rigid body. Their combined mass is 40 kg with mass center at G. The assembly is mounted in bearings A and B, and rotation is prevented by link CD. Determine the magnitudes of the forces exerted on the shaft by bearings A and B while the couple is applied to the handle as shown. Would these forces change if the couple were applied to the shaft AB rather than to the handle?
