· Basically: cut out a part of a truss, and then treat it as if it is a rigid body. When done wisely, this allows simplified solutions. The alternative is using the method of joints to find all (or many) of the forces in the frame.
· Keep in mind that while moments are very popular with the method of sections, it can also be used for forces as well.
· Consider an example where we want to find forces in a structure, ([Hibbeler, 1992], prob 6-24, pg. )
