Draw the given truss with all zero-bars removed. If the structure is stable and statically determinate, solve the forces in all of the bars of the truss using hand calculations. Indicate tension (T) or compression (C). If it is stable and determinate, check your answers using Risa 2D eductional software and print out a screenshot of the deflected shape.
