How do roller coaster designers use math?

Basic mathematical subjects such as calculus help determine the height needed to allow the car to get up the next hill, the maximum speed, and the angles of ascent and descent. These calculations also help make sure that the roller coaster is safe.

Vector calculus is a powerful tool for those in the business of ride design and creation. Calculus methods allow us to determine the maximum height attainable by a roller coaster before the track is even built.

They have to calculate how big to make the hills, how fast the roller coaster will move at various points on the track, and how long the ride should last. The equation at the very heart of all these calculations is a quadratic equation.

Roller coaster engineering falls under the domain of the mechanical engineer. Mechanical engineers apply the principles of engineering, physics, and material science for the design, analysis, manufacturing, and maintenance of mechanical systems.

Introduction. A roller coaster is a machine that uses gravity and inertia to send a train of cars along a winding track. The combination of gravity and inertia, along with g-forces and centripetal acceleration give the body certain sensations as the coaster moves up, down, and around the track.

Roller coasters are designed to run on two basic scientific principles: 1) gravity and 2) the transfer of energy. On Earth, gravity is the force that pulls objects toward the ground. The transfer of energy is what causes objects at rest to move and objects in motion to slow or stop.

It allows you to calculate the Distance, Rate, and Time of any given trip. That means, if you plug in a slower rate for a longer trip, you might find that the longer route actually gets you there faster if it has less construction and allows you to go at a faster rate (speed).

The roller coaster uses a control system that includes Programmable Logic Controllers (PLC) that synch up using a wireless network to control the seven trains operating on the track.

MORE DETAILS

Most roller coasters run by the Law of Inertia. Since an object at rest stays at rest, all roller coasters have to be pushed or pulled to get started.

MORE DETAILS

If the tracks tilt up, gravity applies a downward force on the back of the coaster, so it decelerates. Since an object in motion tends to stay in motion (Newton's first law of motion), the coaster car will maintain a forward velocity even when it is moving up the track, opposite the force of gravity.

Roller coasters rely on gravity to take them to the end of the track. This involves two types of energy, potential energy and kinetic energy.

Gravity, inertia, g-forces, and centripetal acceleration give riders constantly changing forces which create certain sensations as the coaster travels around the track.
