The torque produced by a 2.5-L automobile engine operating at full throttle was measured over a range of speeds (Figure P8.12). By using this graph of torque as a function of the engine’s speed, prepare a second graph to show how the power output of the engine (in the units of hp) changes with speed (in rpm).
