[quote=Anonymous][quote] 1) All of you complaining about the bridge being flimsy must have skipped high school physics. It seems shocking when you look at it but modern bridges are marvels of engineering that rely on balance and tension. The cards these houses are built with are strong and sturdy but a bridge is still a house of cards. If you take out a keystone, an arch falls. It doesn't mean the arch is weak. Bridge pilons are bridge keystones. [/quote] +1 I admit I skipped high school physics but I still know what a cantilever span is.[/quote]
