When performing finite element analyses, simple checks must be completed to validate the results (especially as the models become more complex.) In this simple truss analysis, the reaction forces can be easily determined using hand calculations. The reaction forces on the left pin should be 0 N in the x-direction and 5000 N in the ydirection, while the right roller should only have a reaction force of 5000 N in the y-direction. Is your analysis valid based on these hand calculations? What other simple calculation could be done to validate this model
