Centre of gravity
The centre of gravity of an object is basically where all its weight acts, or where all the mass is acting.
Moments around the centre of gravity
Section titled “Moments around the centre of gravity”The moments need to add so that the resultant moment is zero.
Basically, the clockwise moments need to equal the anticlockwise moments.
Formula
Section titled “Formula”Because both moments must be equal, we can describe two objects of
