Question
Design a rigid flange coupling to transmit a torque of 228N-m between two coaxial shafts. The
shaft is made of alloy steel, flanges out of cast iron and bolts out of steel. Four bolts are used to
couple the flanges. The shafts are keyed to the flange hub. The permissible stresses are given
below:
Shear stress on shaft =100MPa
Bearing or crushing stress on shaft =250MPa
Shear stress on keys =100MPa
Bearing stress on keys = 250MPa
Shearing stress on cast iron = 200Mpa
Shear stress on bolts =100MPa >
Provide FBD
