Question

Moment of Inertia is the integration of the square of the distance of the centroid and the del area along the whole area of the structure and this moment is at a distance from the rotating axis, known as the radius of gyration.

(a) True

(b) False

This question was addressed to me in an internship interview.

The above asked question is from Radius of Gyration of an Area in section Moments of Inertia of Engineering Mechanics

Answer 1

Right answer is (a) True

Best explanation: The moment of inertia of the section is the integration of the square of the distance of the centroid and the del area along the whole area of the structure. 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.
