Key Concepts

Tension and Compression

Tension and compression refer to the types of internal forces experienced by the members in a truss. Tension occurs when forces stretch the members, effectively pulling them apart, while compression involves forces that shorten or push the members together. Recognizing whether a member is in tension or compression is crucial for assessing the structural performance and safety of the truss.

Free-Body Diagrams

Free-body diagrams are graphical representations that isolate a component or joint of a structure and display all the forces acting upon it. These diagrams are essential in truss analysis as they help in setting up the equilibrium equations and visualizing the force distribution, making the process of solving for unknown forces more straightforward.

Static Equilibrium

Static equilibrium is the condition in which a structure remains at rest because the sum of all forces and moments acting on it equals zero. This fundamental principle underlies the analysis of trusses, ensuring that every joint or segment is balanced by counteracting forces, which allows for the systematic determination of unknown forces.

Method of Joints

The method of joints is an analytical technique used in truss analysis where each joint is isolated, and the equilibrium equations for forces in the horizontal and vertical directions are applied. This approach simplifies the process by allowing the forces in each member connected to the joint to be solved step by step.
