Learning Objectives:

Construct Free Body Diagrams $($FBD$)$ for $2$D rigid bodies

Apply the equations of equilibrium to $2D$ rigid bodies at rest.

Eree Body Diagram:Diagram representing the body under isolation and with all the forces acting on it$.$

Support reactions applicable to $2D$ rigid bodies

Roller support

Pin support

Fixed suppo.

Example $2$

Determine the components of the support reactions at the fixed support A on the cantilevered beam.
