no
yes because the pressure or weight on the bridge pushes down and the weight goes down the two sides. the triangle is best when it is in the downward "V" shape.
the answer is to be good
When things are nearly over!
At the time that the bridge was built, technology wasn't good enough to build a tunnel of the necessary length.
The triangle is a rigid shape, more so than a square, for example.
when you decide to build a good jump, you shold make sure you start small, you dig, shape then jump :)
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.
They built the Sydney Harbour bridge for a good reason. If there was no bridge how would u get across to the other side without having to take a ferry.
Disadvantage: An arch bridge requires a very stable foundation. The bridge diverts the tension exerted on it onto the foundations on either side of the bridge. Advantage: It is an economical mom to traverse small distances and is able to cope with bending forces.
First build a regular bridge out of decks than add a bunch of steel in an M shape above it and connect the dots. If that doesn't help than here I found this by searching how do you beat level four of bridgecraft on google http://www.youtube.com/watch?v=VbLMzndV9e4 and yes I copied and pasted that! Good luck!
# 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
To make a strong bridge foundation, toothpick or steel, you should use a triangle based design.
