quick look at how they work. ALL bridges work using compression and tension. – Suspension bridges support tremendous amounts of weight and can withstand the greatest force from nature ...

Press down on the center of the bridge. What happens to the top and bottom notches? Notice how the top notch squeezes together in compression, while the bottom notch spreads apart under tension.

How do they do it? All bridges routinely experience compression and tension. The vehicles that press down on a bridge's roadway compress the top half of the road, causing it to shorten like a ...

If you squeeze a spring, it compresses and shortens, when you pull it apart, it creates tension and the spring lengthens. In both bridge designs, the towers take care of the downward compression ...

At the computers, bridge design software shows the price increasing by the tens of thousands as the designers add more tension (steel) and more compression (concrete). The smallest, a 20-foot ...

Yet, with traditional bridge-building activities using materials such as toothpicks or popsicle sticks, students often don’t get the opportunity to accurately measure tension and compression or ...
