how to find the radius of gyration of bat?

Solution

Solution :

Ok consider a baseball bat is nothing but the perpendicular distance rom the axis of rotation to a point mass that gives an equivalent inertia to the original object.

So now lets consider a baseball bat.

Here the radius of gyration is nothing but the perpendicular distance from a pivot where a point mass will have the same mass as the total mass of the bat wuld be located so that mass moment of inertia of this point mass will be same as mass moment of inertia of the bat.
