The figure shows the cam-spring system that is supported by two bearings. Axial load effects are taken by right end bearing. The motion is transmitted by means of two helical gears. According the data is given in the table below: 1- Determine the shaft dimensions on the basis of static design by using a- Maximum shear stress teory b- Distortion energy thoery 2- Determine the shaft dimensions on the basis of fatigue design.
