What is the other name for the moment of inertia?

The moment of inertia, a crucial concept in mechanics, describes how mass is distributed in a body relative to an axis of rotation. This distribution affects the body's resistance to angular acceleration when subjected to rotational forces. The term "radius of gyration" refers to a different property, specifically how far the mass is concentrated from an axis, which is derived from the moment of inertia but is not an alternative name for it.

All other terms, including modulus of elasticity and weep strength, pertain to different physical properties. The modulus of elasticity relates to a material's ability to deform elastically under stress, while weep strength is not commonly associated with the moment of inertia. Therefore, the correct choice indicating no alternative name for moment of inertia is appropriate, reflecting that "none of these" accurately represents what is commonly accepted in engineering terminology.
