Question

In rotation I = MK2 k stand for what​

Answer 1

Answer:

Radius of Gyration

Explanation:

Radius of gyration of a rigid body about an axis can be defined as the perpendicular distance from the axis to a point on the body where the entire mass of the body is imagined to be accumulated (center of gyration). It is denoted by 'K'

It is related to the moment of inertia (I) of that body by the relation:

I = MK²

Hope it helps.

Have a nice day.

Answer 2

In rotation I = MK² k stands for :​

Explanation:

• The moment of inertia of a body about an axis is sometimes represented using the radius of gyration, I = mk²        
• the radius of gyration as the imaginary distance from the centroid at which the area of cross-section is imagined to be focused at a point in order to obtain the same moment of inertia. k = √ I /m
