Step-by-step explanation:
The development of the automobile had significant economic and social impacts on America. The automobile industry led to the expansion of related industries like glass, steel, rubber processing, and oil. It also brought about the need for public roadways, which led to the growth of infrastructure, motels, and restaurants.
The automobile transformed American life by changing shopping and living patterns, replacing mass transit with private automobile traffic, and creating automobile suburbs.
The assembly line process, perfected by Henry Ford, revolutionized manufacturing. It allowed for mass production of cars at reasonable costs. The assembly line involved workers completing the same tasks repeatedly, which increased production efficiency and reduced the price of automobiles.
Ford's assembly line used heavy steel rails and conveyer belts to move a car's chassis down the line, allowing workers to stand in one place and complete simple tasks as cars moved along the line.
