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.

A problem from my textbook requires me to find the torque about a line. I know how to find the torque about a given point but I cannot see how I can use τ=r×F to find it about a given line.

There are conceptual ways and tricks to figure it out, so I want to share those with you so that going forward we don't have to be so anxious when we're solving a torque problem.

Practice predicting where a force should be applied to keep a bar in rotational equilibrium.

A Ferris wheel is modeled below. Passenger cabins hang from the wheel at rest. Four of the cabins are labelled. Assume all of the cabins are empty and have the same mass. From …

Learn how torque relates to force, position, and angle, and how force diagrams can be used to analyze forces and torques acting on a rigid system. Explore how force and torque can lead to …

For the Torque example problem, how do we know that this axis end isn't at the point where the 1N force is being applied and is at the other end of the rod instead?
