Considering the loading on the bridge, develop a technical report that conveys the following:

$4.$ Cost of the steel and wooden bridge as a function of $,$ considering only the initial material cost $($which includes the cradle$-$to$-$gate embodied energy$)$

$5.$ Cost of the steel and wooden bridge as anction of $,$ considering the initial material cost $($which includes the cradle$-$to$-$gate embodied energy$)$ and the transportation cost to site

$6.$ Recommendation of final design: material choice, optimal $,$ forces, sizes, state, total cost
