Study Notes
Free Body Diagram (FBD)
- A graphical illustration used to visualize applied forces, moments, and resulting reactions on a body in a given condition.
- Depicts a body or connected bodies with all the applied forces and moments, and reactions, which act on the body(ies).
Types of Bodies
- May consist of multiple internal members (such as a truss).
- Can be a compact body (such as a beam).
Purpose of FBDs
- Used to visualize forces and moments applied to a body and to calculate reactions in mechanics problems.
- Frequently used to determine the loading of individual structural components and to calculate internal forces within a structure.
Applications of FBDs
- Used by most engineering disciplines, including Biomechanics and Structural Engineering.
- An important step in understanding mechanics problems in the educational environment.
