Transportation has changed a great deal over time. Early types of transportation included row boats and horse drawn vehicles. People used these types of transportation to move themselves or goods from one location to another. Horses were domesticated to pull a buggy or wagon carrying people and goods. Next came the development of steamboats, automobiles, and locomotives. Steamboats transported people from one location to another, and helped transport people over water easier and faster than previously. Steamboat engines were used in the first automobiles. The engine was so heavy that it didn't allow the cars to move very fast. Over time, the engines were modified and became gasoline powered. This allowed automobiles to travel at faster speeds. Locomotives, although used less today, were once used heavily in the transportation of goods. In fact, some circuses used railroads to transport their crew.

2018.070.004 1932 Chevrolet. Brand new, the car cost $615 in 1932. Only 52,446 were made. This car could seat five people, much like today's cars. The engine is a 6-cylinder with overhead valves. This means instead of the valves sitting on top of the cylinder head, the valves are inside. The 6-cylinders mean that there are six pistons firing in the cylinder chamber, causing the combustion to run the motor . The more cylinders a car has, the more combustion, which gives the engine more horsepower. This car has 60 horsepower and can reach 3,000 RPMs - revolutions per minute, meaning how many revolutions does the pistons take per minute. This car also has a synchromesh transmission to match the gears to speed. This creates a smooth transition between gears. It is also free wheeling and has four-wheel mechanical brakes. This car originally came from Colo, IA.
