he diameter of pulley A is 150 mm and the diameter of pulley B is 480 mm. The allowable tensile stress for the shaft material is 170 MPa and the allowable shear stress is 85 MPa. Taking torsion and bending factors as 1.25 and 1.75 respectively, find the shaft diameter. Also find out the dimensions for a hollow shaft with outside diameter limited to 30 mm. Compare the weights of the two shafts. [Ans. 30 mm ; 24 mm ; 1.82 Given
The shaft, is driven by pulley B from an electric motor. Another belt drive
from pulley A is running a compressor. The belt tensions for pulley A are 1500 N and 600 N. The ratio
of belt tensions for pulley B is 3.5.
The diameter of pulley A is 150 mm and the diameter of pulley B is 480 mm. The allowable tensile
stress for the shaft material is 170 MPa and the allowable shear stress is 85 MPa. Taking torsion and
bending factors as 1.25 and 1.75 respectively, find the shaft diameter.
Also find out the dimensions for a hollow shaft with outside diameter limited to 30 mm. Compare the
weights of the two shafts. [Ans. 30 mm ; 24 mm ; 1.82
