Activity 2.1.6 Step-by-Step Truss System Introduction Truss systems are essential components within structural systems ranging from residential construction to large scale civil engineering projects such as bridges. Regardless of the system application, trusses are designed to utilize material strength, reduce costs, and support a determined load. Engineers must be able to understand how loads act on a truss structure and within the structure to ensure design feasibility and safety. Activity 2.1.6 will guide you through the step-by-step process of calculating reaction forces and member forces within a truss system. Equipment Straight edge Calculator Pencil Procedure In this activity you will calculate reaction and member forces for the truss system illustrated below. To ensure proper calculations and free body diagrams, it is essential that you follow each step in the procedure
