The IS 2021 (Impeller shaft) of a fluid agitator transmit 31 kW at 510 rpm. Given that the allowed shear stress in the impeller shaft must be limited to 95 MPa, solve for the percent savings (in percent) in weight if the hollow shaft is used instead of the solid shaft Note: Outside diameter of the hollow impeller shaft must be 50 mm. HINT: % savings = Cross-sectional area solid -Cross-sectional area Cross-sectional area solid hollow
