A hollow shaft is to transmit 300 kW at 80 rpm. If the shear stress is...

The power transmitted by a shaft can be expressed as:

P = 2 * pi * T * n / (9.55 * d)

where P is the power transmitted in kW, T is the shear stress in MN/m^2, n is the speed in rpm, and d is the diameter of the shaft in mm.

Since the shear stress is not to exceed 60 MN/m^2, we can set T = 60 MN/m^2. The speed is 80 rpm, and the power transmitted is 300 kW. We can use the above equation to solve for the diameter d:

300 kW = 2 * pi * 60 MN/m^2 * 80 rpm / (9.55 * d)

d = 300 kW * 9.55 / (2 * pi * 60 MN/m^2 * 80 rpm)

= 300 kW * 9.55 / (2 * 3.14 * 60 MN/m^2 * 80 rpm)

= 0.1591 m

= 159.1 mm

The external diameter of the shaft is 159.1 mm.

Since the internal diameter is 0.6 of the external diameter, the internal diameter of the shaft is 0.6 * 159.1 mm = 95.46 mm.
