Example V $-$ Group Problem $(1$ of $2)$

Given: The frame supports external

load as shown.

Find: The support reactions at A$,$ B$,$

and $C$ and the horizontal and

vertical components of pin

reactions $D.$

Plan:

a$.$ Draw FBDs of the frame's members.

b$.$ Apply the equations of equilibrium and solve for the

unknowns.

c$.$ Sketch the solution and confirm that each free$-$body is in

equilibrium.
