Method of joints example 2

The video tutorial demonstrates how to apply the method of joints to solve a challenging truss problem. The goal is to find the internal force in member BC. The process begins with analyzing the geometry of the truss, followed by examining joint A to determine forces AB and AC. The tutorial then moves to joint B, where the forces BD and BC are analyzed. The calculations reveal that member BC is a zero-force member, meaning it has no internal force. The tutorial emphasizes the importance of understanding trigonometry and equilibrium equations in solving such problems.
