The power output of an autmobile engine is advertisted to be 220 hp at 600 rpm. (Remeber 1 hp = 7446 Watts)
a) What is the corresponding torque of this engine at that rpm?
b) You could apply this much torque if you placed a heavy weight at the very end of a long horizontal wrench. If the weight had a mass of 45 kg, what would be the wrench handle-length needed?
