The document explains the mechanism of a roller coaster. It consists of a series of connected cars that move along a track powered by gravity and momentum. Traditionally, the cars are pulled up a hill by a chain lift to gain potential energy. Some newer designs use a catapult launch system instead, such as a linear induction motor that uses electromagnets to rapidly accelerate the train and build up kinetic energy. The train is slowed down at the end of the track and at other points using a hydraulic brake system with clamps positioned along the track.

ROLLERCOASTER MECHANISM

2. OBJECTIVE
Explain the mechanism used for a roller coaster

3. DEFINITION
Roller coaster is an amusement ride developed for amusement
parks and modern theme parks. It consists of a track, with one
or more inversions known as a loop.
The ride may not sometimes always have a complete circuit.
Most roller coasters have multiple cars where passengers sit
and are strapped in securely to enjoy the ride. Therefore when
two or more cars are hooked together they are known as a
train.

4. MECHANISM
Consists of a series of connected cars that move on tracks.
The ride is moved with the help of gravity and momentum.
Therefore to build the momentum the train needs to get to the
top of the first hill or give a powerful launch.
The traditional lifting mechanism is a long length of chain
running up the hill under the track.
In some newer coaster designs, a catapult launch sets the
train in motion

5. CATAPULT LAUNCH LIFT
Instead of dragging the train up a hill
to build up potential energy, these
systems start the train off by building
up a good amount of kinetic energy in
a short amount of time.
Popular catapult system is the linear-induction
motor. A linear-induction
motor uses electromagnets to build
two magnetic fields.
One on the track and one on the
bottom of the train, that are attracted to
each other.

6. BRAKE SYSTEM
This system is very simple. A series of clamps is positioned at
the end of the track and at a few other braking points.
A central computer operates a hydraulic system that closes
these clamps when the train needs to stop.
