I know that when a body is is equilibrium
There is zero resultant force in any direction, i.e. the sum of all the components of all the forces in any direction is zero
The sum of the moments about any point is zero (this point does not need to be on the body)
What if the body is not in equilibrium?
Let me clarify: What if there is a resultant moment of $5\text{ Nm}$ clockwise about a point on a body. If I calculated the moment about another random point in or outside the body, would I still get $5\text{ Nm}$ clockwise as my value?
