16.4 THE METHOD OF JOINTS

· The basic steps when solving problems with the method of joints is,

1. Draw an FBD for each joint as if it is a particle.
2. Solve for the applied forces with the "joint particle" in equilibrium. The simplest joints are often the best to start with.

· We can see an example of a two force member below being used to support a canopy,

· This method is best shown using a sample problem, ([Hibbeler, 1992], prob 6-7, pg. )

· This problem can also be solved using matrices techniques by framing the truss members as linear equations.
