In analyzing or designing trusses, it is necessary to determine the force in each member of the truss. One way to do this is the method of joints. The method of joints is based on the fact that if the entire truss is in equilibrium, each joint in the truss must also be in equilibrium (i.e., the free-body diagram of each joint must be balanced). Consider the truss shown in the diagram. The applied forces are P = 630 N and P = 350 N and the distance is d = 2.25 m. (Figure 1) igure 1 of 1 В 30° 30° C d P2
