Torque and Rotational Dynamics

Twisting effect a force has around an axis of rotation.

Summary

• Only the force component perpendicular to \vec r generates torque.
• Magnitude of torque: \tau=rF\sin \theta=rF_\perp
• Torque is at its largest when the force is applied 90$\degree$ to r.
• Force diagrams are like FBD but shows how each force acts relative to the axis.
