	For an object to remain fixed in this way, forces acting on it must cancel each other out ''(e.g. all downward forces must be equalled by upward forces)''.

	A See-Saw can be made to balance, or remain in '''Equilibrium''', if the person sitting on one side, tending to make it turn clockwise, exerts exactly the same force as the person on the other side tending to make it turn anti-clockwise. In addition, the central support must be able to resist the total load exerted by both.
