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.

ƩFx= 0
ƩFy= 0
ƩM= 0
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.
