Rolla+coasterr's

Though the Roller coaster's origin is Russian, but we are going to skip a couple of centuries and go straight into the American Roller Coasters. The Mauch Chunk railway is the origin of the American Rollercoaster phenomena. However this railways intentions was not for fun, it was a resourceful to travel coal down the hill without using a lot of man power thet men would load the car with coal and push them down the 17-18 mile track then mules would carry the carts back up the mountain and then repeat the process. Later on, the men decided to transport the mules back down also and later on people therefore the ride became instantaneously popular. Soon the mules replaced by steam engines and the Mauch Railway was made purely for enjoyment it is stated to be approximately 40 miles in length reaching top speeds of 100MPH. In other words really really really fast. Sense this was such a great success, in 1884 Mr. Thompson designed the Pleasure Switchback railwayat Coney Island. This coaster was able to hold ten passengers and reach top speed of six miles per hour. Yet, even with such small speeds the coaster made an average of $600 dollars daily. In competition with the Pleasure Switchback railway Charles Alcoke designed a oval track that would hold six passenger and speeds that doubled that of the Pleasure SwitchBack. This new railway was known as the Serpentine railway. The first railway with linking cars, tunnels, and had people facing forward was the Scenic railway of Atlantic City New Jersey. Thompsons second railway also included a new safety feature which prohibitted the coaster to roll in the reverse direction. In 1888, the first looping track was invented and called the Flip-Flap but because the loop was a perfect circle the passenger experienced neck problem thus, leading to the fall of the Flip-Flap. Then in 1901 the Loop-da-Loop was invented this time the loop was a ellipical shape yet, the coaster only held four people therefore leading to its demise. Them after WWI came the roaring twenties a time where everyone was living as if it where there last therefore stimulating the roller coaster industry up to as many as 2000 roler coasters where built. But they soon fell due to the great depression, WWII, and the television. Nobody wanted to ride rollercoasters anymore.Therefore, giving Walt Disney all the ingredients to serve up a brand new idea called a theme park. His theme park was called Disneyland which he constructed rides that compiled of steel sleds that ran on tubular tracks and nylon wheels thus destroying a lot of friction. These rides where the prototype for the modern day rollercoasters in style, speed, and safety.media type="file" key="physics.wmv" They put upside down loops at the beginning of the track because the cart does not have much acceleration therefore the centrifugal forces of the loop would not snap the riders necks. If farmin' engineering was askedto make sure the coaster was secure we would have safety harnesses, neck rest, clamps that made the coaster to ride on the track, and a sensor that would slow down the coaster once it hit a danger zone in g forces.The gpe or gravitational potential energyis the greatest at the crest of the hill and the kinetic energy is greastest at the bottom of the hill. At the top of the hill is where you will feel weightless.
