Question

radius of gyration with reference to centroidal x - axis of a plane geometrical figure having area A is​

Answer 1

Answer: The answer is $k = \sqrt{\frac{I}{A}}$

The radius of Gyration: The distance a body's whole mass may be concentrated without affecting its moment of rotational inertia around an axis through its center of mass is known as the radius of gyration.

Explanation:

• Formula for the moment of Inertia I = A X K² where A is area of plane body and K is the radius of gyration
• therefore K = $\sqrt\frac{I}{M}$
