Static Equilibrium and Torque Problems

This video discusses the concept of “static equilibrium”, when the forces and torques on an object are balanced, and walks through 4 common types of physics problems related to torque and static equilibrium. For more of my videos related to rotational motion SEE BELOW… What is Torque?

The linked video covers the definition of rotational inertia, how to find it experimentally, how to calculate it from different equations, and include 2 example problems. Below are also three videos that allow you to investigate the relationship between the torque exerted on a system and the system’s angular acceleration. This is the experiment I use to introduce my students to the concept of rotational inertia. The linked conclusion discussion explains how the concept of rotational inertia is related to the collected data.
