Moment of inertia, also calledmass moment of inertia,rotational inertia, or theangular mass, (SIunits kg·m2) is a measure of an object's resistance to changes in itsrotationrate. It is the rotational analog ofmass, theinertiaof a rigid rotating body with respect to its rotation. The momen...

Calculations involving kinetic energy are usually easiest in body coordinates, because then the moment of inertia tensor does not change in time. If one also diagonalizes the rigid body's moment of inertia tensor (with nine components, six of which are independent), then one has a set of ...
Since the moment of inertia of a surface is its area multiplied by the square of a length called the radius of gyration, the above formula may be rearranged as follows. Using the Euler formula for hinged ends, and substituting A·r2 for I, the following formula results....
Mathematical analysis of buckling makes use of an axial load eccentricity that introduces a moment, which does not form part of the primary forces to which the member is subjected. When load is constantly being applied on a member, such as column, it will ultimately become large enough to ...
