An engine delivers 75 hp of power to a rotating shaft. If the shaft rotates at 2500 revolutions per minute, determine the torque exerted on the shaft by the engine.
Given: W?rs = 75 hp = 41,250 ft-lbf/s; N = 2500 rpm = 41.67 rps
What will be an ideal response?
From Problem 2.44, T= Wrs/2?N = 158 ft - lbf
