The area moment of inertia (also called the second moment of area) defines the resistance of a cross-section to bending, due ...

Angular momentum (I will refer to its traditional name) also depends upon two things: the angular velocity and the moment of inertia. Typically, textbooks use the letter L to represent the angular ...

Let's review a bit of physics in preparation for Part 2 of our technology ... moments of inertia (MOI) and crankshafts Visualize a spinning crankshaft, acting about its rotational axis.

Crucially, the further away mass is positioned from an object's axis of rotation, the greater the moment of inertia. Thus, for commonly handled objects like smartphones, this resistance to ...

For one of the sticks, take two water bottles and tape them ... If each mass has a distance r from the axis of rotation then the moment of inertia can be calculated as the sum of the products ...

The answer has to do with rotational inertia, a property shared by all rotating ... Credit: Jose Rivas Move the marbles 6 mm closer to the axis of rotation, and repeat steps 1 and 2. Continue ...

But the quake's interference with our axis doesn't stop there. The Japanese landmass was moved around by as much as 4m. This redistribution of mass on the surface changes our moment of inertia.
