and new weapons for armies. Explorers established trade routes to redistribute raw materials and finished products. Modern culture is also influenced by the availability of new materials. In the 1960's plastics were used to make colorful toys and housewares at such a low cost that they were frequently disposed of and replaced with the latest style.

Materials engineers are involved in the development, processing, and testing of the materials used to create a range of products, from computer chips and aircraft wings to golf clubs and snow skis. They work with metals, ceramics, plastics, semiconductors, and composites to create new materials that meet certain mechanical, electrical, and chemical requirements.
· In civil engineering, a Motorscraper or Wheeled Tractor Scraper is a piece of heavy equipment used for earthmoving. The scraper can transport its load to the fill area where the blade is raised, the back panel of the hopper, or the ejector, is hydraulically pushed forward and the soil or clay load tumbles out.
