SUMMARY
To convert a uniformly distributed load on a truss into point forces at pin joints, first calculate the resultant force of the distributed load, which acts downward at the midpoint of the truss. This resultant force can be treated as a single force applied at the middle joint in the negative y-direction. Additionally, it is essential to analyze the moments caused by the distributed load to determine the forces acting on each joint in both the x and y directions.
