An electric motor purchased by your employer surprisingly arrived without a keyway in the shaft. The motor has power rating of 7.5kW & 1,800rpm & has a shaft of Ø17mm. It will be used to drive a centrifugal pump using cast iron sheave. Design the square key to be used in the assembly based on maximum bearing & shearing stresses of 580MPA & 370MPA, respectively, and factor of safety of 5.
