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.

Homework Equations





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.

If you want your matrix data to come out unskewed, try posting it using [/CODE] tags:

Code:
27.56   39.46   57.20
33.29   27.80   99.60
22.10   45.54   69.60
If you can't post your problem or your attempt at a solution, there's not much we can do to help.
