The response of a component to these torsional loads depends upon a material property called the shear modulus, and the geometry of the component through its geometric moment of inertia. In these ...

The area moment of inertia (also called the second moment of area) defines the resistance of a cross-section to bending, due to the shape of the cross-section. It is a key parameter for the ...

After the stool is spun, the person brings his/her arms closer to the body. By moving masses closer to axis of rotation, the moment of inertia of the system is decreased, so the angular speed of the ...
