Homework Statement
A bridge truss extends x = 214 m across a river (Fig. P12.68) where θ = 35°. The structure is free to slide horizontally to permit thermal expansion. The structural components are connected by pin joints, and the masses of the bars are small compared with the mass of a 1270 kg car at the center. Calculate the force of tension or compression in each structural component.
Homework Equations
Lami's Theorem
A/sin a = B/sin b = C/sin c
The Attempt at a Solution
I found the forces in most of the members except T_AC and T_CE.
How do i find the force? Should I use moment equation? Is so how should I apply it?
