Ferris wheels are one of the most iconic amusement park attractions, capturing the hearts and imaginations of people around the world. These giant structures provide riders with stunning views of the surrounding area and a thrilling experience that combines excitement and wonder. But have you ever stopped to wonder how Ferris wheels actually work? In this blog post, we'll take a closer look at the science behind Ferris wheels, including their mechanics, physics, and design.

How do Ferris wheels work?

At their core, Ferris wheels are simply a collection of wheels connected to a central axle, with cabins or other seating arrangements placed around the outer rim. As the wheel rotates, the cabins move up and down, providing riders with a constantly changing view.

But how does the Ferris wheel manage to stay upright and stable? The key lies in centripetal force, which is the force that acts on a rotating object, pushing it towards the center of the rotation. In the case of Ferris wheels, the centripetal force is generated by the rotation of the wheel itself, with the cabins and other components acting as weights that are pulled towards the center of the wheel.

To ensure that the Ferris wheel remains stable, engineers must carefully balance the weight of the wheel and the cabins, making sure that the center of gravity remains in the center of the wheel at all times. They also use a range of other mechanical components, such as bearings and gears, to ensure smooth and safe rotation.

Design considerations for Ferris wheels

When designing Ferris wheels, engineers must consider a range of factors, including the desired size and shape of the wheel, the number of cabins or seats, and the intended use of the ride. One key consideration is the height of the wheel, which can impact the amount of force generated by the rotation of the wheel and the stability of the ride.

Another factor to consider is the shape of the wheel itself. Some Ferris wheels, such as the observation wheel, are designed to provide riders with a more comfortable and stable experience, while others, such as the transportable Ferris wheel, are designed for easy transportation and setup.

To ensure the safety and reliability of Ferris wheels, engineers also conduct extensive testing and simulations, using advanced computer modeling and real-world tests to identify potential issues and ensure that the ride is safe and stable for riders.

The physics behind Ferris wheels

To understand the physics behind Ferris wheels, we need to look at the various forces involved in their motion. One of the most important forces is gravity, which acts on the cabins and other components of the ride, pulling them towards the center of the earth. Friction is another key force, as it helps to slow down and stop the rotation of the wheel.

Tension is also an important force in Ferris wheel motion, as it acts on the cables or other components that hold the cabins in place. By carefully managing tension and other forces, engineers can ensure that the ride is safe and stable, even at high speeds and altitudes.

Another key concept in Ferris wheel physics is torque, which is the force that causes an object to rotate around an axis. In Ferris wheels, torque is generated by the weight of the cabins and other components, which act as a lever, rotating the wheel around the central axle.

Innovations in Ferris wheel design

As technology and engineering continue to advance, we are seeing a range of exciting new innovations in Ferris wheel design. One of the most interesting is the development of solar-powered Ferris wheels, which use solar panels to generate the electricity needed to power the ride.

Another innovation is the integration of roller coasters into Ferris wheels, creating a hybrid ride that combines the thrill of a coaster with the breathtaking views of a Ferris wheel. These hybrid rides can be especially exciting, as they combine the best of both worlds, providing riders with a unique and unforgettable experience.

In addition to these technological innovations, we are also seeing more creative and unique Ferris wheel designs, with some rides incorporating interactive features, such as virtual reality experiences or interactive games. These features can add an extra level of excitement and engagement to the ride, making it more enjoyable and memorable for riders.

The future of Ferris wheels

As Ferris wheel technology continues to advance, we can expect to see even more exciting and innovative designs in the future. With the development of new materials, advanced computer modeling and simulation tools, and other engineering innovations, the possibilities for Ferris wheel design are virtually limitless.

One area of particular interest is the development of sustainable Ferris wheels that are powered by renewable energy sources, such as wind, solar, or hydroelectric power. These rides could be a powerful symbol of our commitment to sustainability and our efforts to reduce our carbon footprint.

Another area of interest is the use of advanced technologies, such as virtual reality and augmented reality, to enhance the Ferris wheel experience even further. These technologies could allow riders to explore new worlds and experiences, providing a completely immersive and unforgettable ride.

Ferris Wheel Physics

There is no better example of physics at work than to look at amusement park rides. From the mechanical engineering feats that make a roller coaster, to the physical trickery of carnival games, a fairground is the most practical example of physics in action. Take the ferris wheel, for instance. If you have ever been on a Ferris wheel ride, you have been the subject of centripetal acceleration at work.

How does a Ferris wheel work?

Before you build a Ferris wheel you must first understand Ferris wheel physics. Ferris wheels are large, non-building structures that rotate about a central axis. Seats are attached to the outer rim of the wheel and always hang downwards. This is because as the Ferris wheel spins the seats, or gondolas, can freely rotate at the support where they are connected to the wheel. The Ferris wheel spins upwards with the help of gears and motors, while gravity pulls the wheel back down again. This cycle continues for the duration of the ride.

The interesting part comes into play when you realize that you feel lighter at the top of the Ferris wheel, and heavier when you are at the bottom. But how can that be? After all your mass never changes at different points during the revolution; that is where centripetal acceleration comes into play.

Physics 101: Terminology

To learn how a Ferris wheel works we first need to understand some basic physic terms:

Acceleration: The rate of change of velocity with respect to time. If an object is speeding up, slowing down, or changing direction, it is accelerating or decelerating. Acceleration describes the rate of change of both the magnitude and the direction of velocity. Acceleration = Force divided by mass or a=F/m.

Force: An influence on an object which causes a change in velocity, direction, or shape. Force equals mass times acceleration or F=ma.

Gravity: The force that tends to draw objects towards the center of the Earth.

Mass: The amount of matter within an object is called mass. The terms mass and weight are often used interchangeably. However, weight=Mass x Gravity, thus mass can never be zero while weight can be zero when no gravitational forces are acting upon it, such as in outer space.

Inertia: The tendency to resist change in motion. Inertia is the embodiment of Newton’s first law: an object at rest stays at rest and an object in motion stays in motion with the same speed and the in the same direction unless acted upon by an unbalanced force.

To explain this, let’s think about an environment free of gravity (a force) like space. If you throw a ball in space, it will theoretically fly through the air forever in the exact direction and the exact same speed with which you threw in. However, if it came into contact with an unbalanced force such as a meteor, it would change its direction

Centripetal Acceleration: The definition for centripetal acceleration is: the acceleration toward the center that holds a satellite elliptical in orbit. In Laymen’s terms, it is the force that keeps a smaller object orbiting a bigger one. Think of it like the solar system. The Earth orbits the Sun thanks to centripetal acceleration. The equation for centripetal acceleration is:  a = W2*R, where W presents the angular velocity of the Ferris wheel in radians and R is the radius of the Ferris wheel. Thus you can see how important it is for an observation wheel with a large radius to turn slowly because the rotation rate  will have a significant impact on the centripetal acceleration.

How does this apply to Ferris wheels?

A typical Ferris wheel rotates at a constant speed (unless stopping to let passengers off). But velocity is speed with a direction vector attached to it, so velocity is changing every second. Your bodies’ “apparent” weight varies depending on the place you are on the ride. You can feel your “true weight” when the centripetal acceleration is pointing horizontally and has no vector component parallel with gravity. It has no contribution in the vertical direction so this is affected when you are exactly halfway between the top and bottom.

At these two positions centripetal acceleration presents a vector which is parallel with gravity, so they can be directly added together.

Force at the Top of the Wheel

At the top of the circle centripetal acceleration  is pointing directly down.  F1 is the force exerted on the passengers at the top of the wheel. F1=m(g-a). Standing on the Earth we are at 1g. At the top of the Ferris wheel the passengers may experience 0.5g, thus they feel lighter (but remember their mass is the same).

Force at the Bottom of the Wheel

When you reach the bottom of the Ferris wheel, the ride becomes more exciting because of the fact that both forces, rotation and weight combine what results in greater acceleration or g force, meaning you feel heavier.  At the bottom of the circle centripetal acceleration, which always points towards the center of the circle, is pointing directly up. F2=m(g+a).  At the bottom of the Ferris wheel the passengers experience 1.5g and they feel heavier.

Conclusion

Those are just a few of the forces at work on a Ferris wheel. There is much to be learned from amusement parks other than pure entertainment. Now that we understand Ferris wheel physics, we can begin to learn how to build and operate one safely. Read more about Observation Wheel Technology.

The Difference Between a Ferris Wheel and Observation Wheel

The Difference Between a Ferris Wheel and Observation Wheel

When the Ferris wheel was created, it inspired awe and wonder. As the popularity of Ferris wheels grew, creations of taller, grander wheels became a way for people to enjoy the carnival ride on a bigger scale. Our SkyWheel is no exception! But what is the difference between a Ferris wheel and an observation wheel? 

What is an Observation Wheel?

Observation wheels are gaining popularity all around the world. From the London Eye to the High Roller in Las Vegas, these attractions offer a new experience from your average fair ride. A giant observation wheel is a type of Ferris wheel in the form of a large, enclosed observation wheel with passenger gondolas. These can include luxury seats, or a standing room. Their basic structure consists of a rotating wheel mounted to a central supported structure. The great height of these rides allow for a beautiful view of your surroundings – like the shores of Myrtle Beach! 

What is the difference between an observation wheel and a Ferris Wheel?

Modern observation wheels are typically much larger than the Ferris wheels they evolved from. Observation wheel’s capsules are usually enclosed, air conditioned, and sometimes private. This allows year-round operation unlike Ferris wheels. Ferris wheels are generally cheaper and smaller in size, making them popular for small carnivals and amusement parks. 

Think of comparing the two like comparing go-karts to nascar racing. Go-karting is a smaller, easier, and quicker way to experience racing down a track. Nascar is more classic and grand experience. While they both fall under the same definition of racing, one allows the full experience on a much more massive scale. Observation wheels are just the modernized version of the Ferris wheel.

Aspects of an Observation Wheel

Observation wheels are typically overlook scenic areas. They scale much larger than your average Ferris wheel, allowing you to view more distance from the top. Our own SkyWheel reaches nearly 200 feet tall. Thin cables to stabilize an observation wheel gives it a transparent look. Gondolas are used rather than carts, allowing a relaxing and comfortable experience on the wheel. These structures are made for viewing and experiencing the world surrounding you. They offer a more grand and memorable experience.

Aspects of a Ferris Wheel

We have all seen a basic Ferris wheel. These rides are typically found at attractions like fairs, amusement parks, and small events. While the height of a Ferris wheel can reach rather high, they are usually shorter and closer to the ground. This is because Ferris wheels typically offer open-air gondolas or carts rather than enclosed spaces. To make it easier to travel, Ferris wheels are sometimes made to be transported for other events. Observation wheels remain in one location.

About: Ferris wheel

A Ferris wheel (also called a Giant Wheel or an observation wheel) is an amusement ride consisting of a rotating upright wheel with multiple passenger-carrying components (commonly referred to as passenger cars, cabins, tubs, gondolas, capsules, or pods) attached to the rim in such a way that as the wheel turns, they are kept upright, usually by gravity. Some of the largest modern Ferris wheels have cars mounted on the outside of the rim, with electric motors to independently rotate each car to keep it upright. These cars are often referred to as capsules or pods. The original Ferris Wheel was designed and constructed by George Washington Gale Ferris Jr. as a landmark for the World's Columbian Exposition in Chicago; however, wheels of this form predate Ferris's wheel by centuries. The generic term "Ferris wheel," now used in English for all such structures, has become the most common type of amusement ride at state fairs in the United States. The tallest Ferris wheel, the 260-metre (853 ft) Ain Dubai in the United Arab Emirates, opened in October . The previous record holder since had been the 167.6-metre (550 ft) High Roller in Las Vegas, Nevada, which opened to the public in March .
