WORLD HISTORY

Detailed explanation-1: -Manufacturers implemented mass production through division of labor, assembly lines, large factories, and specialized machinery-requiring huge financial investment. Henry Ford and his engineers applied techniques developed in the automobile industry to revolutionize tractor production.

Detailed explanation-2: -Interchangeability can be defined as it is a system of producing the mating parts. A single operator was confined with a number of units to assemble it which will take a long period of time and it won’t be economical. To reduce the cost and time, mass production of the system was developed.

Detailed explanation-3: -Advantages of interchangeability It allows mass production, reduces the production cost. Mating parts can freely replace without custom fittings like fillets. Readily available replacement component in the market. Assembly process requires lesser skill.

Detailed explanation-4: -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.
