The method of sections is used to find the force in a

specific member of a truss and is based on the
principle that, if a body is in equilibrium, then every
part of that body is also in equilibrium. When applied,
the method of sections "cuts" or sections the
members of a truss and exposes their internal forces.
To find the unknown internal member forces, the free-
