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-body diagram of a section is drawn and the equations of equilibrium are applied: Part B £F, =0 EF, =0 As shown, a truss is loaded by the forces P = 492 lb and P = 197 lb and has the dimension a = 10.3 ft 本 EMo=0 Because there are only three independent equilibrium equations, section cuts should be made such that there are not more than three L. members that have unknown forces. al2 al2 Determine Foc and FCH. the magnitudes of the forces in members CG and GH, respectively, using the method of sections.

I Review FBC = 197 lbs Previous Answers Learning Goal: To apply the method of sections to find the forces in specific members of a truss. Submit v Correct 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 Part B exposes their internal forces. To find the unknown internal member forces, the free-body diagram of a section is drawn and the equations of equilibrium are applied: ΣΕ-0 As shown, a truss is loaded by the forces P = 492 lb and P = 197 lb and has the dimension a = 10.3 ft EF, = 0 E Mo =0 Because there are only three independent equilibrium equations, P1 section cuts should be made such that there are not more than three members that have unknown forces.
