Ʃ(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Bridge consist of two identical segments M and N connected by rods as shown in the picture. Each rod makes angle of 45° with the horizontal line.

Determine the axial forces in each rod due to the load P at point G.

2. Relevant equations

ƩF_{x}= 0

ƩF_{y}= 0

ƩM= 0

3. The attempt at a solution

I have tried with cutting the bridge into 2 parts to get a result. But basically I am unable to solve the problem on my own. I think it somehow involves using moments.

I would be grateful for any help.
