1.Answer the following questions.
a)A solid shaft transmits 75kW power at 200rpm.Determine thediameter of the shaft if the twist in the shaft is not exceeded10 in 1m length of the shaft, and shear stress islimited 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 twistingmoment. Allowable shear stress in the material is 70N/mm^2 andtwist in a length of 2.5m is not to exceed 10.Determinethe maximum external diameter of the shaft satisfying theseconditions. Take modulus of rigidity G= 80KN/mm^2
