As a design engineer of a certain company, you are required to design a cast iron unprotected type flange coupling that will connect a drive motor to a compressor. The coupling must be able to transmit a power of 21.72 kW at a speed of 350 revolutions per minutes. During the start-up. the motor shaft transmits a maximum torque that is 35 % greater than the normal torque. The coupling flanges are fitted with 4 bolts. The safe shear stress for shaft material is 80 MPa, Safe shear stress for bolt material is 56 MPa, Safe shear stress for cast iron coupling is 14 MPa an Safe shear stress for key material is 60 MPa.
