Radius of GyrationMediumQuestion 30316

Question

The radius of gyration k of a body is defined by:
  1. A
    I = mk²
    Correct
  2. B
    I = m/k²
  3. C
    I = mk
  4. D
    k = I/m

Correct answer

I = mk²

Explanation

Radius of gyration k: I = mk². It is the distance at which the entire mass can be concentrated to give the same moment of inertia.
