what size shaft is required to transmit 100 Hp @ 1000 rpm ,if max shear stress is 10,000 psi .angle of twist must be less than 1 degree /ft .shaft is made of steel.

The formula for calculating the required shaft size is: Shaft diameter (inches) = 0.00019 x HP x RPM
To determine the torque required, use the formula: Torque (lb-ft) = (HP x 5252) / RPM = (100 x 5252) / 1000 = 525.2 lb-ft
Yes, the material of the shaft can affect the required size. Different materials have different strength and stiffness properties, which can impact the shaft's ability to transmit power.
The standard safety factor used for determining the required shaft size is typically 2 to 3. This ensures that the shaft can handle the expected load and any unexpected stresses without failure.
Yes, there are other factors that should be considered such as the type of loading (constant or fluctuating), the operating conditions (temperature, vibration, etc.), and the design of the shaft (keyways, bearings, etc.). These factors can impact the required size and should be carefully evaluated.
