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
