Academics

Question: 1. A 302 stainless-steel shaft has the following specifications. Outside diameter = 0.500 in

Inside diameter = 0.375 in

Length = 3.25 in

Loading = varying rpm = 10 000

Find a. Maximum safe horsepower.

b. Angle of twist (degrees).

2. A gear transmitting 18 kW at 130 rpm is fastened to a 75-mm-diameter AISI 1045 steel shaft by means of an AISI 1045 steel flat key 20 mm wide by 12 mm thick. If the permissible shear and bearing stresses are 55(106) and 110(106) Pa, respectively, what length of key is required?
