3/86 The shaft, lever, and handle are welded together and consitute a single rigid body. Their combined mass is 28kg with mass centre at G. The assembly is mounted in bearings A and B, and rotation is prevented by link CD. Determine the forces exerted on the shaft by bearings A and 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?

4/109 Determine the compression force C exerted on the can for an applied force P=50N when the can crusher is in the position shown. Note that there are two links AB and two links AOD, with one pair of linkages on each side of the stationary portion of the crusher. Also, pin B is on the vertical centerline of the can. Finally, note that small square projections E of the moving jaw move in recessed slots of the fixed frame. Ans: C = 249 N
