Truss Example Part 1

The video tutorial explains how to find internal forces in a truss assembly. It begins with drawing a free body diagram, followed by calculating reaction forces using equilibrium equations. The tutorial then focuses on analyzing joint A to determine the internal forces in the truss members, identifying whether they are in tension or compression.
