define radius of gyration. give it's physical significance?
Answers
Answer:
Radius of gyration of a body about an axis of rotation is defined as the radical distance of a point from the axis of rotation at which,if whole mass of the body is assumed to be concentrated,it's moment of inertia about the given axis would be the same as with its actual distribution of mass.
Answer:
Radius of gyration is defined as the distance between the axis of rotation and the point at which whole mass of the body is the suppose to be concentrated,so as to have same moment of inertia as that of body.
Explanation:
significance:
Moment of inertia of a body about a given axis depend upon the mass of the body and distribution of mass about the axis of rotation.
Moment of inertia is expressed as the mass and square of particular distance from axis of rotation.
