Question

A shaft is required to transmit 300 KW power at 220 rpm.
Maximum torque may be 1.5 times mean torque. Shear stress in the shaft should exceed 45 N/mm^2 and twist 1 degree per meter length. Determine diameter of Hollow shaft with external diameter twice internal diameter. Take G 80 N/mm 2. In this Example max torque will be

O 13.02*10^6 N mm
O 10*10^6 N mm
O 19.53*10^6 N mm
O 12*10^6 N mm

Answer 1

A shaft is required to transmit 300 KW power at 220 rpm.

O 13.02*10^6 N mm

O 10*10^6 N mm

O 19.53*10^6 N mm

O 12*10^6 N mm
