Force analysis using a large matrix.

Homework Statement

Perform analysis over the simplified bridge structure shown. F_1 is the wind load and F_2 is the combined center of gravity of all loadings on the bridge. You are told that F_2 is usually constant but F_1 can vary with time. Note that Members AB, BE, CE and CD are all of the same length.

Perform equilibrium analysis on each joint and show that the reaction forces and the internal forces can be obtained by solving the following matrix equation.

I tried copying and pasting the matrix data, but it didn't come out nicely.

The Attempt at a Solution

Yet to attempt anything as I'm not sure how to. Also the gigantic matrix is quite intimidating. It's been some time since learning matrix mathematics and I don't recall a whole lot of it.
