Particle Equil Ex Prob 13 Truss Joint Analysis

We have been working a sequence of 2D Particle Equilibrium problems, starting with cables, then adding solid links, in tension and/or compression. We've worked multi-node problems. We've learned about finding a node at which we can start, and then stepping node by node through the problem. All of these skills and steps are exactly what is done in Chapter 6 (Hibbeler) Truss Analysis for the Method of Joints. So we're introducing a simple truss here to illustrate the process and to lay a foundation for Chapter 6 Truss Analysis.
