Sum of moments about a point

Web20 Feb 2024 · To expand our concept of rotational inertia, we define the moment of inertia I of an object to be the sum of m r 2 for all the point masses of which it is composed. That is, I = ∑ m r 2. Here I is analogous to m in translational motion. Because of the distance r, the moment of inertia for any object depends on the chosen axis. WebRemember that any force vector that travels through a given point will exert no moment about that point. To write out the moment equations simply sum the moments exerted by …
