The evolution of automobiles began with Henry Ford in the early 1900s. The automaker recognized that the process of walking between stands was wasting time and creating production jam-ups. In 1913, Ford introduced the first moving assembly line in Detroit. The moving assembly line moved vehicles past a stationary assembler, reducing the assembly task for each worker from 2.5 minutes to under two minutes. This new system also allowed the moving assembly line to pace the stationary worker. The first moving assembly line consisted of metal strips.
Modern automobiles are a complex technical system
Today’s automobile is a highly complex technical system that uses thousands of parts and dozens of subsystems to function as a whole. Some of these systems are specialized and control one part of the car, while others are used for more generalized functions. The system’s overall performance, safety, and overall health depend on the interplay of these systems. Here we will discuss some of the most important automotive systems and how they work together.
They are a major form of transportation
Today, there are many types of transportation, but none is more ubiquitous than the automobile. One third of the land in Los Angeles is paved for automobile travel. The city is notorious for traffic congestion. Although cars have been around for less than a century, they have had a profound impact on American culture and society. Today, a family in the U.S. spends more on transportation than it does on food. The automobile industry provides 10% of U.S. jobs, but recent gas prices have made it more economical to use mass transportation.
They are a major source of pollution
The automobile is one of the largest sources of pollution in the world. The automobile not only pollutes the air, but also changes space. It takes human and machine labor to manufacture one, releasing a wide range of pollution along the way. Automobiles are also one of the biggest consumers of oil, and their production results in increased consumption of petroleum products. It is therefore crucial to reduce the impact of automobiles on the environment.
They have enabled farmers to increase the quantity and quality of their foods
With the advancement of technology, farmers are able to cultivate larger plots of land while requiring less labor. New government policies also encourage farmers to expand their operations to increase the amount of food they produce. The resulting economies of scale allow a chicken farmer to earn more profit per bird. Today, the decisions of where and how to grow food have shifted from households to corporations.
They have led to a shift from an economy of scarcity to one of affluence
The increase in automobile ownership has spawned a new consumer class that has far-reaching effects on economic activity across the globe and on the environment. Although new consumers make up just one eighth of India’s population, they account for more than half of its private spending on transportation. This new consumer class accounted for 85% of India’s private transportation spending in the late 1990s. The global carbon footprint associated with this growing class of consumers has been estimated to be about 15 times higher than the rest of the population.
