1.Answer the following questions.

a)A solid shaft transmits 75kW power at 200rpm.Determine the diameter of the shaft if the twist in the shaft is not exceeded 1⁰ in 1m length of the shaft, and shear stress is limited to 50N/mm^2.

Take rigidity modulus, G=100kN/mm^2

b)A hollow shaft with a diameter ratio of 0.7(internal outside) is required to transmit 500kW at 300 rpm with a uniform twisting moment. Allowable shear stress in the material is 70N/mm^2 and twist in a length of 2.5m is not to exceed 1⁰.Determine the maximum external diameter of the shaft satisfying these conditions. Take modulus of rigidity G= 80KN/mm^2
