Notice how the top notch squeezes together in compression, while the bottom notch spreads apart under tension. Pre-stressed concrete is an ideal material for beam bridge construction; the concrete ...

Although professional engineers might be more concerned with steel beams in a bridge, you can do ... putting some of the strands in tension and some in compression. Which ones break first depends ...

How to build a stable bridge is what this game is ... what we’re given in these simulations, the compression and tension forces will cause the beam to collapse under its own weight (causing ...

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 ...
