Problem 22.1 The shaft shown is supported by self-aligning bearings at A and B. The balls which are inside the bearing are shown at A and B. (Self-aligning here means that the bearings can provide reaction forces, but not reaction moments.) Belt forces are applied as shown. The left end of the shaft beyond the bearing is connected to a clutch by means of a flexible coupling, so that only a torque can be transmitted there. The right end beyond the bearing is free. Neglecting stress concentrations, calculate stresses on element S on the "side" of the shaft and summarize the results with a stress element sketch. • Neglecting stress concentrations, calculate stresses on element T on the "top" of the shaft and summarize the results with a stress element sketch. 100 mm 20 mm dia 100 mm B Free end of shaft 2000 N

two cylinders are connected to form a parallel cylinder actuatingsystem. Assume the bore and rod diameters of the left cylinder are 120 mm and 60 mm, respectively, and that those of the right cylinder are 100 mm and 50 mm. If the mass of the external loads to be driven by the left and right cylinders are 750 and 500 kg, respectively, and the back pressure in both rod-end chambers is 200 kPa, calculate the operating pressure of each cylinder for driving the loads.

The picture shows the rear swivel axle bearing design of a 4-wheel wagon. It is known that the speed of the wagon wheels is n = 37 rpm. The total radial load carried by the wagon is given as Fr= 16060 Newtons. In addition, due to road conditions, Fa axial load is applied to the wagon.
