The Torque Wheel provides an easy method for creating an equilibrium among several non- parallel torques, Figure 5.4 shows a force F applied at an angle 0 to the 1ine from the center of the Torque Whecl to the point of application of the force. The worque can calculated as T-F d sin e. However, as shown, d sin e is just the perpendicular distance, d between the center of the Torque Wheel and the line of the force, when that line is extended back.
