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...

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...

A hollow shaft is to transmit 20 kW at 300 rpm. The loading is such that a maximum bending moment of 1000 Nm is induced in the shaft, together with an additional axial thrust of 15 kN. The shaft is supported on bearings 1500 mm apart. The values of shock and fatigue factors in torsion and bending (Kt and Kb) are 1.25 and 1.75 respectively. The inside diameter is 0.8 times the outside diameter. Determine the outer diameter of the...

Question: Analyse the efficiency of transmitting power using a solid shaft of diameter "d" compared to a hollow shaft of diameters "Do" and "Di". The ratio "r" = Do/Di should be varied from 1.5, 1.6, 1.7, 1.8; 1.9; and 2.0 but the weight of the hollow shaft must be equal to the weight of the solid shaft. Assume the length of the shaft between the two bearings (see figure below) to be the same. must be until you find the...
