Information:
- Designed by structural engineer George Washington Gale Ferris Jr., the Ferris wheel rotates upwards with the help of gears and motors and is pulled downwards by gravity.
- An example of a gear and axle is a ferris wheel, a simple machine consisting of two interconnected rings or cylinders, one inside the other, that rotate in the same direction around a single center point.
- The working principle of a ferris wheel is to use an electric motor to decelerate through a reducer, converting high speed and low torque into high torque and low speed mechanical power. It is transmitted to the wheel disc through an intermediate mechanism such as a tire that is both elastic and has a certain strength, making it rotate at low speed
- The forces are not balanced on the Ferris wheel. Circular moving objects have a “centripetal force” and this force always points to the center of the circle. Ferris wheel physics deals with centripetal acceleration.
- To ensure the Ferris wheel remains stable, engineers must carefully balance the weight of the wheel and cabins, ensuring that the center of gravity remains centered at all times. At the top of the Ferris wheel, the normal force points up and the gravitational force points down. The sum of these two forces must equal the centripetal force pointing downward towards the center of the circle.
- We feel lighter at the top of the Ferris wheel and heavier at the bottom. Because the normal force of our seat increases and the centripetal force pulls us upwards.
Targeted Gains:
- Makes predictions about how the direction of a force can be changed and tests its predictions.
- Calls the tools used to change the direction and/or magnitude of a force simple machines.
- Realizes that an “output” force greater than the “input” force applied can be obtained by using a simple machine.
- States that using a simple machine while doing a job will not save energy, it will only provide ease of doing work.
- Makes a design that will increase the magnitude of the output force by applying a certain input force to a compound machine consisting of at least three simple machines.
- Investigates different types of simple machines and evaluates the benefits that simple machines have offered to humanity in the past and today.
- Explains the functions of simple machines used in daily life.
- Designs and builds a simple machine that can solve a problem in daily life.
