| - | Which member (beam) is under most compression (positive $f_i$)? Which member (beam) is under most tension (negative $f_i$)? | + | A positive value of $f_i$ indicates the member (beam) $i$ is under tension, and negative $f_i$ indicates compression. Which member is under most tension? Which member is under most compression? |
| One of the main challenges of this problem is figuring out how to enter the elements of the matrix quickly and reliably. For a small matrix, it's easy to type out the matrix explicitly like ''A = [ 1 9 7 ; 4 3 8 ; 6 2 0]'', but for a 13 x 13 matrix with 169 elements, that's tedious and error prone. | One of the main challenges of this problem is figuring out how to enter the elements of the matrix quickly and reliably.
