Case 1: Case of the Twisted Shaft The shafting shown in Figure 2.51 was taken from a mill transfer chain that was frequently overloaded, causing the shaft (made of low-carbon steel) to fail by torsion shear. It has obviousły been loaded in torsion beyond its elastic limit into the plastic range and has taken a permanent set. Since the sprocket and bearing bores are not easily changed to sub- stitute a larger diameter shaft, what type of replacement shaft will solve the problem? What different mechanical proper- ties must it possess so it will not again fail by torsion shear?
