Question
(10) A 40mm diameter shaft is driven @ 3,600rpm by a 150kW motor. The shaft drives a 400mm diameter chain sprocket having an output efficiency of 85%. Determine (a) the torque of the shaft in kN-m (b) output force on the sprocket in kN; (c) power delivered by the sprocket in kW; (d) if the given diameter is safe to use for the said application if: - allowable torsional deflection of 1° based on 20 times its diameter; - maximum allowable stress is 70MPa; - modulus of rigidity is 85x103MPa
