i 1 Question 1 If you ordered the bars in the same order as the nodes (starting with bar 1 between nodes 1 and 2), 1 1 1 1 0 0 0 0 1 0 0 1 1 1 1 0 0 A = 2 0 0 0 0 1 1 1 1 1 1 0 0 0 0 1 1 You’d still get credit if you used a different order. There were many ways to give an independent set of solutions. Here’s one independent set: the entire truss moves to the right the entire truss moves up the truss rotates clockwise about the origin nodes 1 and 3 move out, nodes 2 and 4 move in The vectors corresponding to those solutions would be the columns of this ma- trix: 1 0 1 0 0 1 0 1 1 0 0 1 0 1 1 0 1 0 1 0 0 1 0 1 1 0 0 1 0 1 1 0
