Question

The radius of gyration is related to the moment of the body. So the calculation of the moment of the body due to the loadings involve a quantity called ____________

(a) Moment

(b) Inertia

(c) Moment of Inertia

(d) Rotation

I got this question in quiz.

Origin of the question is Radius of Gyration of an Area topic in chapter Moments of Inertia of Engineering Mechanics

Answer 1

Correct answer is (c) Moment of Inertia

The explanation: The calculation of the moment of the body due to the loadings involve a quantity called a moment of inertia. This is having much significance in the various fields in the engineering sector. The main types are the ‘I’ section structures which are being much used.
