Spinning Roller Coaster

The charm of the great circle is that it has put rich elements into a short track. In a few seconds, the force acting on the passenger is constantly changing, so that people can experience a variety of different feelings. When these forces are applied to all parts of the body, the eye will see the whole world upside down. For many roller coaster passengers, the top of the loop is the most wonderful moment in the whole running process. People will feel as light as feathers and can only see the sky in their eyes.

In the large loop, the strength of vertical acceleration is determined by two factors: the speed of the train and the angle of the curve. When the train enters the loop, it has the maximum kinetic energy, that is, it moves at the fastest speed. At the top of the loop, gravity has reduced the speed of the train to a certain extent, so the train has more potential energy, but the kinetic energy is reduced, that is to say, it moves at a lower speed, but the speed can not be lower than a safe driving speed.

Roller coaster designers are the first to use a circular loop. In this design, the angle of the curve along the way is a constant. In order to generate enough vertical acceleration at the top of the loop to press the train close to the track, designers have to let the train enter the loop at a fairly fast speed (so that the train can still move quickly at the top of the loop). Faster speed means more force on the passengers as they enter the loop, which can make them uncomfortable.

The drop shaped design makes it easier to balance these forces. The curve angle at the top of the loop is faster than that at the side of the loop. In this way, the train can pass through the loop at a speed fast enough to have enough acceleration force at the top of the loop, and the water drop design will produce a small vertical acceleration at the side. This provides the force needed to keep the roller coaster running without putting too much force on the potentially dangerous parts.

Once the roller coaster has finished its journey, the brake will stop the roller coaster very safely. The speed of deceleration is controlled by the pressure of gas in the brake cylinder.
