we use wood for make bridge strong
a truss
Put many straws together to make it stronger
because of the support of the circles
it is a hybrid between an arch bridge and truss bridge. so it is classified as an arch and truss
Glenville Truss Bridge was created in 1885.
A truss is a diagonal brace which provides structural support for a bridge span by extending between a vertical member and the bridge span.

the truss
In general, a truss bridge is stronger than a beam bridge due to its design, which distributes loads more efficiently through a series of interconnected triangles. This triangular configuration allows truss bridges to handle greater loads and spans compared to beam bridges, which rely primarily on the strength of a single horizontal beam. Additionally, truss bridges tend to be lighter, making them more cost-effective for longer spans. However, the specific strength can also depend on materials and construction methods used.
The type of bridges are: -truss bridge -arch bridge (truss arch bridge) -suspension bridge (suspension truss bridge) -cantilever bridge
the first Truss bridge was built by Palmer in 1811 in Philidelphia
