Design & draw a protective type CI flange coupling for a steel

Design & draw a protective type CI flange coupling for a steel shaft transmitting 15 kW at 200 rpm & having an allowable shear stress of 40 MPa. The working shear stress in the bolts shouldn't exceed 30 MPa Assume that the same material is used for shaft & key & and that crush- ing stress is twice the value of its shear stress. The max. torque is 25% -greater than the full load torque. The shear stress for CI is 14 MPa
