Annealed stainless steel shaft drives the propeller on an inboard boat motor. The shaft sas a 25 mm outside diameter and a 15 mm inside diameter. The shaft transmits 5000 W of power to the propeller at a speed of 400 rpm. Due to the propeller thrust, the shaft is also under an axial compressive force of 1000 N. Using the Von Mises failure criteria, determine the safety factor on the shafi
