1) Analyze the deformation of the truss of constant cross section A = 1mm², with a tensile load of F = 1N. Material is aluminum, E = 70GPa. Compare your results to the expected results.

2. Redo the study above but let the area of the 6-cell truss reduce to 80% of the original cross section. How many percent is the elongation as compared to results of case 1. Deformation should be bigger.

3. Let the total load of 1N be spread out. Node 1 is locked, Node 2 to Node 5 is elongated with a total load of 1N but in each node (position) with 1/6 N. What is the deformation in each cell as compared to case 1?
