An engine produces 400 kW of power which spins a shaft at 6000 rpm (revolutions per minute). Note that 1 kW = 1000 W. a) What is the total torque produced by the shaft? b) Assuming the shaft has an allowable shear stress of 350 MPa, what is the minimum required diameter of the shaft if it were designed as a solid rod? c) If the shaft was to be redesigned as a hollow rod with an outer diameter equal to 1.5 times your solution for (b), what would be the maximum required inner diameter for the same allowable shear stress?
