Control the force or torque of a joint

This example shows how to apply a constant torque to a hinge joint.

Prerequisites

Create the required basic physics, including:

• The rigid bodies
• The collision bodies
• The basic joint with fixed joint properties

Steps

To create a Hinge Joint and apply torque to it, do the following:

1. Choose Home tab → Mechanical group → Basic Joint.
2. Create the joint with the following physical properties:
   • Basic Joint list = Hinge Joint
   • 1 = Attachment
   • 2 = Base
   • 3 = Axis Vector
   • 4 = Anchor Point
3. In the Name group, type a name for the hinge joint, and then press Enter.
4. Click OK.
5. Choose Home tab → Electrical group → Force/Torque Control.
6. In the graphics window, select the hinge joint.
7. In the Constraints group, set Torque to 5.
8. In the Name group, type a name for the controller, and then click OK.
9. Choose Home tab → Simulation group → Play.

In the simulation, torque is applied to the hinge joint, causing it to rotate under the specified constant torque value.
