Answer:
Most economists recognize three factors or production: land, labor, and capital.
Of these, land is the hardest to change because it has a fixed supply (there is a definite amount of land available on earht).
Capital is the second more mobile, although some forms of liquid capital like cash, can be even more mobile than labor.
And labor is usually the most mobile and easiest to change (not always), because people often change jobs, and move in specific segments of the labor market.
During the Industrial Revolution of the 19th century, machines took over most of the manufacturing work from men, and factories replaced craftsmen’s workshops. The event that laid the groundwork for this monumental change was the introduction of interchangeable parts, or pre-manufactured parts that were for all practical purposes identical, into the firearms industry. 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.
