A circular shaft has to transmit 550kW power at 115 RPM. Allowable shear stress=78 MPa. Find i) The required diameter of solid shaft ii)The diameters of hollow section section such that internal diameter=0.75 x external diameter.

given data : power transmitted P = 550KW Number of rotations N = 115rpm

i) Here what to be found out is the diameter of the solid shaft. This can be found by using torsion equation $${T\over J}= {\tau\over R}$$ torque can be calculated by the formulae $$P= {2\pi\ NT\over60}$$ …
