A cantilevered stepped shaft is made of steel having yield strength of 700 MPa. The shaft diameters are 36 mm and 30 mm with a fillet radius r=3 mm. The shaft is subjected to a transverse load F-5 kN and a torque T-800 N.m a) Find the strength factor of safety based on the distortion-energy theory and compare it with the maximum shear stress theory. b) Find the maximum torque that can be applied to the shaft based on the stress concentration chart shown.
