By 1919, The roller coaster was first developed by John Miller. In 1927, A roller coaster was placed at an Amusement Park, the Cyclone was placed and the Coney Island. The roller coaster has a monumental ice slide, the height is 70 ft, it was popular in the 16th and 17th centuries in Russia. The first roller coaster(American) was the Mauch Chunk Switchback Railway. It was built in the mid-1800’s in the mountains of Pennsylvania.
“With the Great Depression and World War II, roller-coaster production declined, but a second roller-coaster boom in the 1970s and early 1980s revitalized the amusement-park industry.” They were introduced to innovative tubular steel coaster, by this era. The most popular roller coaster were in Amusement parks in the United States such as in Kennywood park in Pennsylvania and Coney Island in New York. There were around 2,000 working roller coasters by 1920’s.
Many roller coaster carts are tied up with a chain called the chain dogs sturdy hinged hooks. The linear-induction motor uses electromagnetic. The electric magnetics are used to build two magnetic fields….one if them is on the bottom of the train and the other one is on the track. The main advantage of the roller coaster is its speed, efficiency, durability, precision and controllability. The popular system of the roller coaster has use of dozen of rotating wheels, they help the train up the hill, which are arranged in two rows along the track. The wheels grip the bottom (or top) of the train between them, pushing the train forward. Of course every roller coaster needs brakes.
The breaks on the roller coaster helps the roller coaster stop after the ride….and just in case of an emergency. The brakes aren’t built into the train itself “they’re build into the train.” the central computer operated hydraulic system that closes the clamps when the train needs to stop. The vertical metal fins close up on the clamps. The roller coasters tracks is served to channel the force, it control the way the roller coaster cars falls. If the roller coasters track is slope down, the gravity pulls the front of the car toward the ground, so it accelerates. If and only the roller coasters tracks tilt up, its gravity applies a downward force on the back of the roller coaster, so it decelerates. “When the coaster ascends one of the smaller hills that follows the initial lift hill, its kinetic energy changes back to potential energy. In this way, the course of the track is constantly converting energy from kinetic to potential and back again.”
