Truss analysis using the method of Joints involves determining the forces in each member of a truss by analyzing the equilibrium of each joint individually. In this method, the truss is broken down into its individual joints, where each joint represents a point where multiple members connect.

Here, you are going to learn how to successfully calculate ana analyze trusses using methods of joints by following the various steps and assumptions in this video below;

Steps:
1. Assume Members in Tension or Compression: Initially assume whether the members are in tension (pulling apart) or compression (pushing together).

2. Isolate the Joint: For each joint, isolate it and consider the forces acting on it. Apply the two fundamental equilibrium equations for a static system:
- Sum of horizontal forces (∑Fx = 0)
- Sum of vertical forces (∑Fy = 0)

3. Solve for Unknown Forces: Start with joints where there are no more than two unknowns, typically at the ends of the truss, and work through each joint in turn to solve for the forces in each member.

The method of Joints is especially useful for calculating forces in smaller trusses and ensures that all members are analyzed accurately for either tension or compression.
