Question

A timing belt that is 98% efficient is transferring power from an electric motor that is supplying 420Nm of torque to a shaft. The shaft is positioned using two deep ball bearings with a friction coefficient of 0.004, 48mm bearing bore diameter and a load of 1900N each. If the pulley on the motor and shaft have 53 and 34 teeth respectively, what would be the torque available at the shaft in Nm?
