USA HISTORY

Detailed explanation-1: -His idea of machine-made, interchangeable parts was the beginning of what would become known as the “American system” of mass production.

Detailed explanation-2: -Mass production methods are based on two general principles: (1) the division and specialization of human labour and (2) the use of tools, machinery, and other equipment, usually automated, in the production of standard, interchangeable parts and products.

Detailed explanation-3: -Interchangeable parts, popularized in America when Eli Whitney used them to assemble muskets in the first years of the 19th century, allowed relatively unskilled workers to produce large numbers of weapons quickly and at lower cost, and made repair and replacement of parts infinitely easier.

Detailed explanation-4: -Mass production benefited from the development of materials such as inexpensive steel, high strength steel and plastics. Machining of metals was greatly enhanced with high-speed steel and later very hard materials such as tungsten carbide for cutting edges.
