radius of gyration

Noun

(physics, engineering) Given a body B, the distance from a given axis of rotation at which a point mass of the same mass as B would have the same moment of inertia about said axis.

Japanese Meaning

(物理・工学) ある物体Bについて、物体全体の質量が一点に集まっていると仮定した場合に、その質量が回転軸から離れて配置される距離として、実際のモーメント慣性と等しくなるような距離を指す（慣性半径）

What is this buttons?

Engineers calculate the radius of gyration to simplify complex mass distributions when analyzing rotational stability.

Sense（1）

(physics, engineering) Given a body B, the distance from a given axis of rotation at which a point mass of the same mass as B would have the same moment of inertia about said axis.

Since the radius of gyration depends on the manner in which the mass is arranged round the axis, it follows that for different axes in the same body there will be different radii of gyration.
