Question

Define radius of gyration and derive a relation for it​

Answer 1

Explanation:

The moment of inertia of a body about an axis is sometimes represented using the radius of gyration. ... We can define the radius of gyration as the imaginary distance from the centroid at which the area of cross-section is imagined to be focused at a point in order to obtain the same moment of inertia. It is denoted by k.

Answer 2

Answer:

Radius of gyration also have mathematical definition. ... k=√IM(1) (1) k = I M This equation (1) is the radius of gyration formula for mass moment of inertia. here, M is mass of the rotating object and I is the moment of inertia about any axis of rotation. In this case it is defined as mass property
