you take wood,glue(wood glue), news paper, the set it up as you want it then glue
make sure you use lots of triangles in your design and make sure you do not use alot of weight
truss brides is similar to liking pie
Triangels are the strongest shape so make a triple triangle design i aced it that way +++ The plank bridge is the weakest as it is just a simple beam with no central support or stiffening for the span. The other two can be designed to comparable strength for a given span, but work in somewhat different ways: the truss bridge acts as a beam stiffened by the truss frames, the arch transmits the forces from the centre to its abutments.
you can check this out link below- its about Truss Bridges
Wilson Pratt Truss Bridge was created in 1904.
the first Truss bridge was built by Palmer in 1811 in Philidelphia
Yes
we use wood for make bridge strong
it helps trains cross since the truss bridge is VERY strong and stable :D
it is a hybrid between an arch bridge and truss bridge. so it is classified as an arch and truss
Warren truss bridge
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 type of bridges are: -truss bridge -arch bridge (truss arch bridge) -suspension bridge (suspension truss bridge) -cantilever bridge
=Yes there are dsiadvantages to a truss bridge, because for all we know all truss bridges are not strong as others are and we can or you can find that out by building your own truss bridge and put a coulpe of things on it to measure it to see if some are strong and some are not.=
