A shaft ABC rotates at 500rpm and is driven through a coupling at the end A. At B a pulley takes off two-third of the power, the remainder being absorbed at C. The part AB is 1.5m long and of 100mm diameter, BC is 2m long and of 75mm diameter. The maximum shear stress set up in BC is 40MPa. Determine the maximum stress in AB and the power transmitted by it, and calculate the total angle of twist in the length AC. Take G = 80GPa.
