Definition of trusses, and their classification into plane and space trusses. Overview of the methods for analyzing trusses: the method of joints and method of sections.
Using the method of joints, a process centering on the joints or connection points between the members, to solve for the unknown forces acting on members of a truss. Includes several worked examples.
Using the method of sections, a process that involves breaking the truss down into sections to each be analyzed as a separate rigid body, to solve for unknown forces acting on members of a truss. Includes several worked examples.
Definition of a frame or machine as a structure with at least one non-two-force member. Distinguishing between frames and machines by structure rigidity.
