A hollow shaft made from AISI 4340 steel has an outer diameter Do of 4 in. and an inne diameter Di of 2.5 in. The shaft rotates at 46 rpm for one hour each day. It is supporte by two bearings and loaded in the middle with a load W of 5500 lb:. The distance betwe the bearings Lis 78 in. The maximum tensile stress due to bending for this type of cycl loading is calculated using the following equation: 8WLD. #(D; – D{) What is the stress ratio for this type of cyclic loading? Would this shaft last for one ye: assuming a safety factor of 2?
