The figure 1 shows a pulley assembly that consists of a shaft supported by two bearings and driven by a motor on the righthand side (not shown in the figure). The shaft diameter is 100mm. The pulley consists of two disks, each disk is 15 mm thick and has an outer diameter of 620mm, that are connected by means of a cylindrical shell. The length of the shell is 500mm, the outer diameter of the shell is 600mm, and the thickness of the shell is 15mm. The pulley drives a belt that places a uniformly distributed load on the shell (of 100000N) as shown in the diagram. The belt lifts a load that applies a torque of 6000Nm to the pulley. The shell and the plates are connected. A 6mm fillet should be applied to all the 90 degree corners between the shaft and the plates and between the shell and the plates.
