33. A cold-rolled steel shaft is used to transmit 60 kW at 500 rpm from a motor. What should be the diameter of the shaft if the shaft is 6 m long and is simply supported at its end? The shaft also experiences bending due to a distributed transverse load of 200 N/m. Ignore bending due to the weight of the shaft. Use a factor of safety 2. The tensile yield limit is 280 MPa. Find the diameter using both maximum shear stress theory and von Mises criterion for yielding.
