the abutments at either end of the bridge anchor the arch so that it will not collapse, the weight of the arch is supported by the abutment on either end
a arch bridge can hold over 6,000 pounds
truss bridges are able to support the most weight applies to the bridge, especially when the weight is applied to the middle
# buy the supplies (Popsicle sticks and glue) # sort the Popsicle sticks from bad ones to good ones. # pick a design (Arch. suspension and box girder) # Build street and support design # wait a day # connect the two # wait a day # build extras # wait 3 days # test bridge
The arch bridge spreads load (the weight of the bridge and the traffic on it) from the deck to the abutments (the supports at each end) and into the ground. This creates a lot of compressions.
is the ponte vecchio bridge is an arch bridge
The brooklyn bridge is not a arch bridge
Arches are among the oldest forms of structural support. Unlike beam bridges, arch bridges are curved. The arch carries the weight outward along the curve to the supports on each end of the bridge, called abutments. The abutments carry the load and stop the bottom of the bridge from spreading out.
if you build an arch bridge it can hold more weight then anyother type of toothpick bridge and can hold about 20lbs (if made well) another good type of bridge is the truss bridge it is just as strong as the arch bridge but it has diffrent structures.
it is a hybrid between an arch bridge and truss bridge. so it is classified as an arch and truss
