Key Concepts

Static Equilibrium

Static equilibrium is the state in which a body or structure remains at rest because the net forces and net moments acting on it are zero. In structural analysis, this principle is used to set up equations that represent the balance of forces and moments, enabling the calculation of unknown support reactions.

Free-Body Diagram

A free-body diagram is a simplified illustration that shows a structure and all the external forces and moments acting upon it, but nothing else. This tool helps in visualizing and organizing the applied loads and support reactions, making it easier to apply the equilibrium conditions correctly.

Support Reactions

Support reactions refer to the forces and moments exerted by the supports on a structure. These are critical in maintaining equilibrium and typically depend on the type of support (such as pin, roller, or fixed), each of which contributes specific reaction components needed to counterbalance external loads.

Equilibrium Equations

Equilibrium equations are mathematical statements derived from the conditions for static equilibrium. They consist of the sum of all horizontal forces, vertical forces, and moments being set to zero. These equations are used systematically to solve for the unknown reaction forces and moments at the supports.
