A hollow shaft 36 inches long transmits 110 HP at 1300 rpm. The shaft is made out of steel with a modulus of rigidity of 11000 ksi. The shaft has an allowable sear stress of 12 ksi and an allowable angle of twist of 2.5 degrees over the 36 inches length. The inside diameter of the shaft is 0.65 that of the outside diameter of the shaft.
Determine:
a) the required inside and outside diameter of the shaft based on shear stress.
b) the required inside and outside diameter of the shaft based on the angle of twist.
Based on shear stress:
Inside Diameter ______ (in.)
Outside Diameter _____ (in.)
Based on angle of twist
Inside Diameter ______ (in.)
Outside Diameter _____ (in.)

Select a diameter of a steel driveshaft that transmits 250 hp at 5000 rpm. Bending and axial load are negligible. Note: Select the diameter as 3 inches What is the nominal shear stress at the surface? If a hollow shaft of inside diameter 0.9 times outside diameter is used, what outside diameter would be required to give the same outer-surface stress? How do the weights of the solid and hollow shaft compare? Rotation unknown diameter 250 hp, n = 5000...
