Learn how to use force diagrams to analyze the forces and torques acting on a rigid system. Explore how force and torque can lead to rolling in different situations.

This is what we learned when we learned moments and torque, but all we did now is we figured out the magnitude of the torque. But what if we wanted to know the direction?

An introduction to torque, a force that causes rotation. Understand how torque is calculated as the product of force and distance, and how it differs from work. Learn about the direction of torque …

Oops. Something went wrong. Please try again. Uh oh, it looks like we ran into an error. You need to refresh. If this problem persists, tell us.

A torque is the rotational equivalent of a force. When a torque is applied to an object it causes the object to rotate. Learn how forces create torques and how to calculate the net torque on a …

Now the direction of your thumb, which is pointing INTO the screen is the direction of torque. I've explained this way to make it easier for you, but if you encounter new problems, first try and …

To produce a torque, the force F must be applied at some distance r away from the pivot point. Since only the perpendicular component F ⊥ produces torque, the equation includes sin θ (see …

When an electric dipole is placed in a uniform field, it experiences a torque. This torque tries to align the dipole in the direction of the field. Let's explore more.

A current-carrying coil kept in a magnetic field experiences a torque, which is the cross product of the magnetic moment and the field vector. Hence, the torque is maximum when the dipole …

David explains how to determine the torque exerted by a non-perpendicular force.
