[[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.
