Page 69 - The moment of a force is said to be positive when it tends to produce right-hand rotation, ie rotation in the direction in which the hands of a clock move, and negative when its tendency is in the reverse direction. If two forces act at different points of a body which is free to rotate about a fixed point, they will produce equilibrium when the algebraic sum of their moments is zero.
