Material Choosing Due To Environment
The environment effects materials over time erosion, switching from hot to cold repeatedly, ext. When a material becomes hot it will expand. So the design also has to have the ability to adjust to hot weather but still be safe for what ever is inside. Cold make objects to shrink so again the design has to be able to shrink and be safe. In road ways in the winter pot holes begin to form because of coldness. Water gets into the cracks of the street and then expands forming a bigger crack, repeatedly this happens forming a bigger hole. Materials in water, especially in the sea, have to deal with erosion. That is when something is worn down slowly by slowly. When the salt in the water keeps hitting the material it takes of a microscopic peace of the material which over time may be worn down. Skyscrapers and very tall buildings have to deal with the wind. They need the ability to sway a tiny bit with the wind. If not the wind could do serious damage. You must use the right materials two if you are building a structure. You cant build a sky scraper out of wood, its not strong enough to with stand wind. The material needed would be steal. Environment will effect almost every material every where. The key in having a safe building is having the right material, but at the same time you have to find the cheapest material to.
