Question
For the truss below, find the reaction forces at pinned joint A and roller joint D. When you draw the FBD, you can represent the reaction force at the roller using a horizontal force acting to the left at D.
Note: The internal forces in the truss members (such as the tension in member AB) does not show up on the FBD; only the external forces and
reactions should appear on the FBD (reactions at A and D as well as the external loads at B and C).
