Moments of Inertia topics include: Moment and product of an inertia for an area, moment of inertia for inclined axis, radius gyration of area, mohrs circle and mass moment of inertia. The moment of inertia, also known as rotational inertia, is a quantity that determines the torque of a rigid body. It is a measure of how much an object resists rotational acceleration about an axis.  The moment of inertia depends on the distribution of mass in an object. The greater the distance the mass is from the center of rotation, the greater the moment of inertia.  There are three types of moment of... Show more
