moment of inertia
noun moments of inertia
-
A measure of a rigid body's resistance to change in its angular velocity around a given axis.
The moment of inertia of a rigid body is a quantity that determines the torque needed for a given angular acceleration about a given rotational axis, analogous to how mass determines the force needed for a given acceleration.
Similar: mass moment of inertia, angular mass, rotational inertia
-
Second moment of area; a measure of a rigid body's resistance to bending.
Stresses due to vertical shearing forces also depend on moment of inertia and are discussed in Chapter 8.
Some mathematicians and stress analysts use the term second moment of area instead of moment of inertia. That term is, in fact, more descriptive of the definition of this property in the followi
