4. TRUSSES

Trusses are essential structures composed of members that only carry axial forces, either tensile or compressive. The stability and determinacy of trusses are determined through the number of joints, reactions, and members, with specific equations of equilibrium applied for analysis. Understanding the principles of truss designs such as the Pratt and Howe trusses allows for effective application in real-world structures.
