- 5.0: Video Introduction to Chapter 5
- Introduction to the topics to be covered in Chapter 5: structures as trusses vs frames and machines; two-force members; methods of analysis for trusses and for frames and machines.
- 5.1: Structures
- Definition of an engineering structure. The classification of structures into trusses and frames or machines.
- 5.2: Two-Force Members
- Definition of two-force members, and how to identify them. The importance of two-force members in truss analysis problems.
- 5.3: Trusses
- 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.
- 5.4: Method of Joints
- 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.
- 5.5: Method of Sections
- 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.
- 5.6: Frames and Machines
- 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.
- 5.7: Analysis of Frames and Machines
- Steps of the process for analyzing frames and machines and determining the forces experienced by each component. Includes several worked examples.
