6. A transmission shaft carries a pulley midway between the two bearings. The bending moment at the pulley varies from 250 N-m to 650 N-m, as the torsional moment in the shaft varies from 80 N-m to 250 N-m. The frequencies of variation of bending and torsional moments are equal to the shaft speed. The shaft is made of steel FeE 400 (Sut = 540 N/mm² and Syt = 400 N/mm²). The corrected endurance limit of the shaft is 350 N/mm² and factor of safety of 2. Determine the diameter of the shaft using the distortion energy theory of failure.
