Question

The measure of the body’s resistance to angular acceleration is called ___________

(a) Mass moment of inertia of a body

(b) Volume moment of inertia of a body

(c) Line moment of inertia of a body

(d) Gauss moment of inertia of a body

I have been asked this question during an online exam.

My doubt is from Mass Moment of Inertia topic in section Moments of Inertia of Engineering Mechanics

Answer 1

Right option is (a) Mass moment of inertia of a body

To explain I would say: The measure is known as mass moment of inertia of a body. It’s very useful in the designing of the structures. It also helps in the determination of the strength of the body. Thus a very useful thing in structural engineering.
