In a state of bewilderment one fine day, I asked a group of three mechanical engineers at this company where I was then employed if they could please explain to me the concept of “moment of inertia”.

Explore the fascinating physics behind the moment of inertia on an inclined plane in this detailed video! We break down the concepts step by step, showing how rotational motion, mass distribution, and ...

While weight and mass might affect how fast an objects falls, moment of inertia is the key to speed today! Much like a figure skater pulling their limbs in to speed up a spin, the more mass an object ...

The case of a pulsating-load testing machine shows how to ballpark qualities that are important for deploying electric motors. Crankshafts in running internal-combustion engines pulsate as well as ...

When I was talking about balancing a stick, I mentioned the moment of inertia. Moment of inertia is different than mass, but I like to call it the “rotational mass”. What does mass do? Things with ...
