Parallel Forces are forces which act in parallel lines, such for example as the weights of the portions that make up any framework or structure on the earth's surface. With the exception of a particular case (see COUPLE), parallel forces have always a single resultant, which is readily found by the method of moments. See MOMENT; also FORCE.
