Architects use the Pythagorean theorem, which is expressed by the equation: a2 + b2 = c2, in designing and computing the measurements of building structures and bridges. One example involves roof design. A gable roof is made of two right triangles, where the base of one right triangle is called the run, the height is called the rise and the slope is called the rafter.Continue Reading
It's easy to compute the measurement of the required rafter of the roof using the Pythagorean theorem. To illustrate, if the roof calls for the pitch to have a 6-inch rise and 12-inch run, the rafter is equal to 13.4 inches when computed using the Pythagorean theorem.
In laying the foundation of a building, it is possible to make each corner a right angle, even without a carpenter's square, using only strings, the Pythagorean theorem, particularly the 3-4-5 special triangle and the architect's supervision. First, mark point A as the spot where a wall is to be built. Use a string to measure out a multiple of three, say 6 feet, and mark the endpoint as B, where B is the corner foundation. Use another string to measure a multiple of 4, say 8 feet, from point B to point C. This is the measure of the second wall. Then, a third string connects point C to A and the length should be 10 feet, a multiple of 5, to ensure that the corner is at a right angle.Learn more about Architecture
One of the best ways to locate covered bridges in Indiana is to travel to Parke County, Indiana: home of the annual Covered Bridge Festival. Other resources for viewing covered bridges include two popular books: "Indiana Covered Bridges," by Martha Williamson Mohr, and Harold Stiver's "Indiana's Covered Bridges: A Sourcebook for Photographers and Explorers."Full Answer >
Arch bridges resist compression extremely well, while suspension bridges provide the best tensile strength. Since compression and tension are opposite in nature, it is not possible to guarantee that one type of bridge is the strongest against both.Full Answer >
There are a number of construction methods used when building bridges but, in general, the central road or path is lowered into place using cranes or rolled across the expanse using cantilevers after the supporting structures have been placed. Techniques often vary based on the size of the crossing, the amount of anticipated traffic and use and types of materials being used.Full Answer >
There are numerous types of bridges, including arch bridges, beam bridges, truss bridges, cantilever bridges and suspension bridges. There are a few other types of bridges as well, but they typically can be listed under the above categories as they are adaptations of these main types.Full Answer >
