Greg wrote the following paper about the science involved in designing roller-coaster rides. Read Greg’s paper and look for any revisions he should make.
It Takes Science
(1) Imagine being on a roller-coaster track. (2) You feel the cars slowly climbing to the top of a large hill. (3) Suddenly the roller coaster plunges steeply.(4) It bends and turns as it swiftly follows the curves of the track. (5) Happy screams fill the air as the brief but good ride comes to an end. (6) Riding on a rollercoaster may last only a few minutes. (7) Planning a new roller-coaster ride, however, takes several years. (8) Designing an exciting roller-coaster ride involves imagination and creativity, but it also requires using science.
(9) Ride design begins with a computer program. (10) The program calculates the forces that will affect the roller-coaster cars as they move along the track. (11) Designers must understand the limits these forces create.(12) Understanding these limits helps designers when they are building and improving roller coasters. (13) Designers use their knowledge of friction, gravity, and the laws of motion to make the ride act in a way they plan. (14) This is the reason there are often large hills on roller coasters. (15) Designers take advantage of gravity to generate speed on their ride as cars descend these slopes. (16) Gravity causes the cars to increase their speed as they go down the hill.
(17) Speed alone is not enough for a fantastic roller coaster, though.(18) Designers often add loops and twists to rides. (19) However, roller coasters must be safe as well as exciting. (20) Friction and gravity are key factors in determining how far designers can push the limits of a ride. (21) Will the cars have enough speed to complete the loop? (22) On the track will the cars during an abrupt turn move too fast to stay? (23) These are questions designers must use science to answer.
(24) Another aspect designers need to consider is which material to use to build the roller coaster. (25) Steel roller coasters can be built with steeper hills than wooden roller coasters can handle. (26) Steel roller coasters are generally faster20 of 24 Set 2Grade 8, Revising than wooden ones. (27) Steel also allows wheels to ride more smoothly over a track than wood does. (28) Additionally, steel is stronger than wood. (29) Steel can withstand the forces of a car pressing against the track in tight turns and loops better than wood can. (30) By using steel, designers can create rides full of drops, twists, and loops.
(31) Even the smallest detail must be considered when building new rollercoasters. (32) Meanwhile, too much paint on a track can cause friction. (33) This is a problem because it affects the roller coaster’s speed. (34) Jeff Pike, president of Skyline Attractions, states, “The one thing that will slow down a steel coaster is a buildup on the track rails.” (35) Paint buildup causes resistance on the wheels of a roller coaster as they roll over the track. (36) A good track will have worn paint.(37) This makes the coaster move more quickly.
(38) As science and technology advance, designers are constantly searching for ways to build faster and more complex roller coasters. (39) “Everybody is going higher and taller,” says Kent Seko, a roller-coaster designer with Arrow Dynamics.(40) Designers aim to set new records with each new roller coaster they design.
(41) The sky is the limit when it comes to roller-coaster design. (42) Yet, one thing remains constant. (43) Science should be used to build a roller coaster.
