Their first holiday season ina team of six home economists answered 11, turkey-related questions from cooks across America. Things have grown a great deal since then: More than 50 phone operators now work out of the Butterball office in Naperville, Illinois—about a minute drive from Chicago—and they answer 10, calls on Thanksgiving day alone.
What is the History behind the roller coaster? Built in the 15th century, the slides were built to a height of between 70 and 80 feet 24mconsisted of 50 degree drop, and were reinforced by wooden supports. Other historians believe that the first roller coaster was built by the French.
How does a roller coaster work? Speeds of some roller coasters exceed 60 miles per hour, but once they are pulled to the top of the first drop, the roller coaster provides all of its own energy. The conversion of potential energy to kinetic energy keeps the roller coaster moving from the start of the ride to the finish.
The running wheels keep the coaster running smoothly on the track. The friction wheels keep the cars from bouncing violently from side to side and the third set of wheels make sure the coaster does not slip off the track, when the car is upside down.
The steel construction makes it feasible to have a dipping, diving and looping ride. What is the role of magnets in Roller coasters?
Many new roller coasters have an immediate launch off, instead of making gradual climb up a hill. This new launch style roller coaster mainly uses magnets to achieve quick acceleration at the beginning of the roller coaster ride. The type of magnets used in a roller coaster may vary, but it depends upon both the negative and positive abilities of magnets.
The quick launch of a roller coaster is due to the magnetic propulsion. This depends on magnets repelling each other rather than attracting. Estimates with very strong magnets suggest that such propulsion could send a roller coaster up to mph in few seconds.
Combining strong magnets with a roller coaster is the efficient way to launch a roller coaster forward rapidly. Also, a roller coaster depends on magnetic braking, where magnets, which attract each other gradually, slow down a roller coaster.
These brakes require less replacement than an ordinary roller coaster brakesand are a cost-effective, energy saving device. Usually, magnets on roller coasters are controlled through automated systems.
When propulsion is needed, magnets with different polarities may push down against the sides of the track to make contact with magnets with opposite polarities.
When attraction is needed, magnets place along the track gradually slow down the coaster. Which is the first roller coaster to use magnetic propulsion?
Other parks have adapted this technique completed in Millennium force, built in at Cedar point, a popular theme park in Sandusky, Ohio, was the first roller coaster to use magnetic brakes. Now, magnetic braking is so popular that it is applied on almost all newly designed roller coasters.
It is also applied in super or hyper coasters.Design a Roller Coaster. Try your hand at designing your own roller coaster. You will be building a conceptual coaster using the physics concepts that are used to design real coasters.
