Question

what is radius of gyration ?
Give its unit

Don't spam plz ! ​

Answer 1

Explanation:

the distance from an axis at which the mass of a body may be assumed to be concentrated and at which the moment of inertia will be equal to the moment of inertia of the actual mass about the axis, equal to the square root of the quotient of the moment of inertia and the mass.

Answer 2

Answer:

Radius of gyration of a rigid body about an axis of rotation is the distance between the axis of rotation and a point at which the whole mass of the body can be supposed to be concentrated b\so that its moment of inertia would be the same with the actual distribution of mass. K = . Its S I unit is m and CGS unit is cm.
