WebThe analysis of a truss should always begin with a joint that has at least one known force and at most two unknown forces. These equations of equilibrium yield two algebraic equations that can be solved for at most two unknowns. As shown, a truss is loaded with forces P1 = 207lb and P2 = 404lb and has the dimension a = 2.90ft. http://web.mit.edu/4.441/1_lectures/1_lecture13/1_lecture13.html
