5/86 The shaft, Iever, and handle are welded together and constitute a single rigid body. Their combined mass is 28 kg with mass center at G. The assembly is mounted in bearings A and B, and rotation is pre- vented by link CD. Determine the forces exerted on the shaft by bearings A atd, B while the 30-N.m 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? Problem 5/86
