THE RUSSIAN MOUNTAINS The first ‘scream machines’ were not out-of-control trains but sleds on man-made ice-covered hills constructed of cut lumber and tree trunks. Elaborate constructions often stretching several city blocks, the 50 mile-per-hour rides earned the nickname ‘Flying Mountains.’ Children and adults would make the tedious trek up 70 feet (five stories) of stairs and climb into an ice-block sled outfitted with a straw seat. The trip back down lasted little more than a few fleeting seconds. Mauch Chunk Switchback Railway Whereas the Russian Mountains is usually credited as the first wheeled coaster, the Switchback in 1784 at St. Petersburg is perhaps more worthy of the crown. Carriages in grooved tracks traveled up and down small hills powered by the height and slope of the initial descent.
Almost 50 years later, the first tracks were laid for the American predecessor of the roller coaster, the Mauch Chunk Switchback Railway in Pennsylvania. Coney Island It began in 1884, when La Marcus Thompson, the ‘Father of the Gravity Ride,’ opened a 600-foot switchback railway at Coney Island. With a top speed of six miles per hour, Thompson’s ride was little more than a leisurely, gravity-powered tour of the beach. Still, its popularity enabled him to recoup his $1, 600 investment in only three weeks. Within a few months, however, Thompson’s monopoly on Coney Island coasters was over. Charles Alcoke also built a slow scenic railway, connecting the ends of the track in a continuous loop in order to return riders to their starting position.
Descriptive Essay: Roller Coaster Ride
When I was younger, I used to love going to amusement parks because roller coasters fascinated me. These beastly machines are usually made of steel or wood, can go as fast as 120 miles per hour, and reach the height of 420 feet. It amazes me why average people like me would trade the tranquility of the ground to be high up in the air, being tossed around with such brutality and roughness, like ...
Although the Alcoke coaster raised the bar, challenging the attendance records of Thompson’s Switchback Railway, it was Phillip Hinkle’s 1885 technological advancement that gave the whole industry a lift. The Hinkle coaster was elliptical and featured a powered hoist that pulled cars to the top of the first hill, making it a far more exciting ride than the slow-moving Switchback. HISTORY OF roller coaster INNOVATIONS The first roller coaster actually built in the United States appeared at Coney Island, Brooklyn, New York in 1884. It was built by La Marcus Thompson, and called the Gravity Pleasure Switchback Railway. Thompson’s ride incorporated flat steel track nailed onto several layers of wooden planks.
Two 45 foot towers were connected with track. The ride reached a top speed of 6 miles per hour, and the train cars had to be manually towed to the top of the hills at the beginning of both tracks; the patrons were required to get out at the end of the first track and climb stairs to the second hill to board the train again for the return trip. Despite this exercise requirement and at only five cents per ride, the Gravity Pleasure Switchback repaid Thompson’s capital investment in less than three weeks. La Marcus Thompson went on to build 24 more roller coasters. The mild nature of this beginning prompted the patent office to name the rides ‘Pleasure Railways,’ a name that persists there (and nowhere else) to this day. Later in 1884, Charles Alcoke designed a coaster with a continuous track, so that the ride ended where it began.
In 1885, Phillip Hinkle used a mechanical hoist to raise the cars to the top of the hill, rather than towing them manually. As early as 1895, designers were experimenting with loops. G-Forces Positive G’sWhen riding a roller coaster, riders will sometimes feel very heavy in their seats. This is caused be positive G’s. Positive G’s occur at the bottom of most hills, and depend on how fast the coaster levels off.
The Essay on Physics Of Roller Coasters
... is sent up the lift hill for another ride” (3). A roller coaster would be nothing without its turns, loops, and tricks and just like ... kinetic energy, gravity, and momentum. Roller coasters use the power from getting to the top of the lift hill or from a powerful ... circle was stretched upward at the top. At one point roller coaster designers abandoned the idea of the loop all together because it caused ...
One G is the pull of normal gravity. Negative G’sNegative G forces are the opposite of positive G’s. These occur when cresting a hill on a roller coaster. Anything below one G is considered a negative G.
At zero G’s it is weightless ness. This occurs because on the uphill, you are still going up, while the train is trying to go down. This creates the common ‘butt out of seat’ thing. Lateral G’sA lateral G is the force that pushes the riders to the side. Lateral G’s occur when the roller coaster is in a corner. Your body is going straight, but the coaster is turning.
Banking the turn (tilting it) helps reduce some lateral Gs. Most of the coasters today have seat dividers which reduce lateral G’s. Compare Coasters Wooden coasters do not have loops. They are usually slower than steel coasters and they seem to sway more. Steel Coasters are far more complex.
They may have loops, turns and all sorts of fun things. They are very solid and more durable than wooden coasters. Wooden and steel roller coasters at Six Flags over Georgia.

Coyote Canyon BlasterSteelFour Lifting Mechanisms of Roller coasters Lift hills, engines, potential and kinetic energyClothoid Loop Roller coasters today employ clotho id loops rather than the circular loops of earlier roller coasters. This is because circular loops require greater entry speeds to complete the loop.
The greater entry speeds subject passengers to greater centripetal acceleration through the lower half of the loop, therefore greater G’s. If the radius is reduced at the top of the loop, the centripetal acceleration is increased sufficiently to keep the passengers and the train from slowing too much as they move through the loop. A large radius is kept through the bottom half of the loop, thereby reducing the centripetal acceleration and the G’s acting on the passengers.

The Essay on Character Analysis of Tom Buchanan from the Great Gatsby
Out of the five main characters in the Great Gatsby, I disliked Tom Buchanan the most ( however his wife Daisy was a close second). He just didn't seem like he was a nice person, and he also seemed extremely self-absorbed. I don't believe that he and I would choose the same values that we would consider important in guiding our lives.One of Tom's important values is wealth. He was very rich and ...
