The stepped shaft rotates at 120 rpm and has a 20 kw input, Ask an Expert

Engineering

The stepped shaft rotates at 120 rpm and has a 20 kW input at A. 16 kW is taken off to operate machinery at B, and the remaining 4 kW is used at C. The shaft is stainless steel with yield strength in shear of 300 MPa.

a. Not including the effect of stress-concentration, what are the minimum allowable diameters for segments AB and BC to achieve a safety factor of 3?

b. With the minimum shaft radii, and now considering stress-concentration, what is the safety factor if the fillet radius is 1 mm?
