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.

What assumptions are made when determining the direction of internal forces?

What does it mean if a member is in tension versus compression?

How do you calculate the internal forces in members AB and AD?

What is the final value of the internal force in member AB, and what does it indicate?
