Question

. A cast iron protective type flange coupling, is used to connect an electric motor to a
compressor to transmit 14 kW at 850 r.p.m. from. The service factor may be assumed as
1.3. The following permissible stresses may be used : Shear stress for shaft, bolt and key
material = 40 MPa Crushing stress for bolt and key = 80 MPa Shear stress for cast iron = 8
MPa also draw a neat sketch of the coupling.
