Hence, make amendments in your testing mechanism accordingly. Nothing heavy really stands on them for a long time. While piling up coins at one point on the bridge, keep this in mind – real bridges mostly have vehicles running across them. Start with a small quantity of water and gradually increase the level. Use refined methods, like suspending a small plastic bucket from different points of the span to identify the weak points if any. It can collapse in no time and more than you not liking it, it’s not at all the correct way of testing the strength of your bridge. Don’t start by putting very heavy objects like bricks over it. For instance, put coins or paper clips one at a time over the bridge to check. Testing the BridgeĪdd a few weights to judge the capacity of the bridge. After construction, run proper tests to check the strength of the bridge. A beam bridge can hold up a great weight albeit for very short distances while suspension bridges can tackle tension and torque (turning effect of a force) effectively over a long distance. The various designs of bridges can be tried to see which structure gives maximum support. In addition to that, natural phenomena like wind currents, rainfall should also be combated. Another force to handle is compression, which tries to exert a push on the bridge and shorten it in the process. It should also have the capacity to withstand tension, that is, the force which tends to pull apart or elongate the bridge. Organizers of most bridge-building contests rank these bridges, highly. The strongest toothpick bridges have very big ratios of their own weight to the maximum weight they can handle. Triangles are known to form very stable structures. You can make a truss out of toothpicks and use as a connector to the two sides.Now join the two sides together by multiple toothpicks to hold the two sides of the bridge. You are done with the other side of the bridge
