Force analysis using a large matrix.

AI Thread Summary
The discussion focuses on performing a force analysis on a simplified bridge structure, considering wind load (F_1) and the constant center of gravity (F_2). Participants are encouraged to conduct equilibrium analysis on each joint to derive reaction and internal forces through a matrix equation. There is a mention of difficulties in presenting matrix data clearly, with a suggestion to use specific formatting for better readability. The original poster expresses uncertainty about how to approach the problem due to intimidation from the matrix size and a lack of recent practice in matrix mathematics. Clear communication of the problem and attempts at a solution is emphasized for effective assistance.

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.

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.

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.
