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 θ to the line form the center of the Torque Wheel to the point of application of the force. The torque can be calculated as π=F d sin θ. However, as shown, d sin θ 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.
Set up the Torque Wheel as shown in Figure 5.5 Use pulleys and hanging masses to apply 3 torques to the wheel.
