TEAEAC:
Mass production and scientific management lowered the cost of car buying so more Americans could afford to buy them. "Early in the century, only the wealthy city dwellers could afford cars." Furthermore, Henry Ford used the idea of mass production to lower the cost, which he made the Model T, so that the average American could finally buy an automobile that they could afford. "The assembly line allowed Ford to keep dropping the sale price." This scientific management technique allowed the cost of Model T to keep dropping because of the assembly line. Further, more and more Americans were able to afford an automobile; in 1919, only 10 percent of American families owned an automobile, by 1927, 56 percent did. Finally, mass production and scientific management did lower the cost of car buying, this allowed Americans to be able to afford a car.
Typewriter:
Typewriter was too heavy (15-25lb) to move often so it was kept on a desk or typing table. Typewriter had a wider platen ( a rubber-covered, steel cylinder for absorbing typing impact) in the carriage (the part that moved the paper into place) that could hold override forms. Portable typewriters were popular for home and school use. Christopher L. Sholes made the first typewriter. Mass production for typewriters made it easier for novelists, writers, and poets to write their stories or even their poetry. Also, it took them less time to do this because of the typewriter and soon everyone wanted one like lawyers, teachers, parents, and the rest of the work force.

Bulldozer:
Popularized in the 1920s, the bulldozer, commonly termed dozer, is a clear offspring of the crawler tractor. Invented by Benjamin Holt, the bulldozer is powerful and necessary tool utilized in almost every construction site. Made with steel plates, giant casting, glass, rubber, plastic components, and with paint. After war, mass buildings were being built and the bulldozer would help to construct the buildings by clearing wrecked parts, putting down dirt, and would lessen the time for constructors to build the buildings.
