Method of Joints: Example
In this example, we will demonstrate the application of the Method of Joints in calculating the internal member forces of the 9-bar truss shown in the figure below. The truss is shown to be under 8 joint forces. We can specify the magnitude and direction of each external force in the LiveMath solution sequence demonstrated below. The solution is broken into two parts
a) Support reactions
b) Axial forces in the nine members
