able torque load the torque required at low speed is very low, but the torque required at high speed is very high. Mathematically, the torque requirement is a function of the speed squared, and the horsepower is a function of the speed cubed. The relationships of torque and horsepower to speed on variable torque loads are shown (Fig. 7).
