Roller coasters are truly a work of art engineers must think hard about,if the ride will be fast enough to go past the obstacles if the passengers will remain safe at all time.Its fascinating history from where it originated from to how it got to its modern day form.To how it works,the physics it has to do the things it does really shows how complicated roller coasters can really be.What is the experience that one engineer had doing a project in a middle school classroom. The direct ancestors of roller coasters are monumental ice slides which are long, steep wooden slides covered in ice,that were popular in Russia in the 16th and 17th centuries.Although roller coasters are not known for using sleds they are known for using carts.This idea became when a few entrepreneurial Frenchmen brought their ideas to France.The warmer climate of France meant that the ice would melt, so the French started building waxed slides instead, eventually adding wheels to the sleds. In 1817 the Russian Mountains of Belleville became the first roller coaster where the train was attached to the track.
By the 1920s, roller coasters were in full swing, with some 2,000 rides in operation around the country(USA).With the Great Depression and World War II, roller coaster production declined but there was a second roller-coaster boom in the 1970s and early 1980s. This era introduced a new form of innovative tubular steel coasters. Some of the most popular ride variations such as the curving corkscrew track saw their days around this time.A roller coaster involves many physics to help it work the way it does.Two main physics are work and energy. At the beginning it has a mechanical device put force on the carts to help them reach the top.Once the reach the top they have built up potential energy(potential energy is energy an object has due to its position) this is due to its height if it is higher it will have a more potential energy.Once it falls down the hill it loses its potential energy and converts it to kinetic energy this is due to it losing weight.
Throughout the ride it gains and loses weight.Once a roller coaster has reached its initial summit and begins its descent through loops,turns and smaller hills the only forces acting upon the coaster cars is the force of gravity. The force of gravity is a force which means that any work done by it does not change the mechanical energy of the carts. The normal force of the track pushing up on the cars is an external force. At a middle school classroom an engineer is told to make a roller coaster made out of the supplies that are available.He is given a group that are talented and creative. With his group they decide how tall there starting will be and how to incorporate their hill and loops.They started off small and decided to make the starting hill and connect it to the loop.
Then they had to adjust the size of the starter to make sure the passenger would make it past the loop.Then decided to make a curve which presented them with a problem they had to make the ride fast enough to go past the loop and to make a curve.So they made the curve go down so the ride would go faster and make the hill at the end.But before they could glue all the pieces together they were told they had to leave.The next day they found that all of their stuff was robbed.The group now had to think of new ways to hold the ride together so it could stand.It took them awhile to figure out what to do but they decided not to stand around all mad but to work so they grabbed random materials they thought could help hold the thing together.Until they had built the things three out of the four team members were happy but felt like they could have done better They tried it out and found that the ride was a success.
They were so happy to have finished with a working ride,but as they put it away they found an error but luckily they were able to fix it. Roller coasters are truly a work of art engineers must think hard about,if the ride will be fast enough to go past the obstacles if the passengers will remain safe at all time.To how it works,the physics it has to do the things it does really shows how complicated roller coasters can really be.What is the experience that one engineer had doing a project in a middle school classroom.If you are looking for a challenge then you should give it a shot at building a roller coaster,you don’t need to spend a lot of money just get materials that you find lying around.
