Method of sections example 1

The video tutorial explains how to find the internal force in a truss member using the method of sections. It begins with an introduction to the problem, followed by a detailed analysis of the geometry and angles involved. The tutorial then covers force analysis and the strategic selection of sections for simplifying the problem. Finally, it demonstrates solving for internal forces using moments and equations, emphasizing the importance of a systematic approach.
