Answer:
Explanation:
he urban landscape became a key driver of industry. Young and aspiring businessmen flocked to the city because it became a source of wealth. There, they could raise the necessary capital for their business ventures.
As a result, cities became central business hubs. New York City grew in epic proportions. The population exploded from slightly over 500,000 people to 3.5 million individuals from 1850 up until 1900. Chicago, America’s heartland, became one of the fastest growing cities in the nation during the last half of the 19th century. This city expanded at an absolutely rapid pace from only 100,000 people to over 1.2 million.
Structural steel aided in the construction of high-rise skyscrapers. This new, stronger kind of steel was a revolutionary product. Structural steel was also excellent for fireproofing. This kind of steel was different than the Bessemer steel used for railroad tracks. Industrialist Andrew Carnegie jumped on the structural steel bandwagon. He redesigned his factories, and replaced his Bessemer converters with the open-hearth process.
Structural steel was higher quality, and a key player in the construction of new skyscrapers. By 1920, more Americans were living in cities than in the countryside thanks to these developments. The steel industry was a major player in making this happen. Its contributions to construction and infrastructure led to increased connectivity and productivity.
