A bridge truss extends $x=206m$ across a river $($shown in the figure below$)$ where $=36.$ 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 $1400$ kg car at the center. Calculate the force of tension or compression in each structural component $($in N $).$

$T_{AB}=,N$ compression $V$

$T_{AC}=,N$ tens

$T_{BC}=,N$ tension $V$

$T_{BD}=,N$ compression $V$

$T_{DE}=,N$ compression $V$

$T_{DC}=,N$ tension

$T_{EC}=,N$ tension $V$
