The Epic Gamer – Rube Goldberg Machine
The Epic Gamer
Goal: The end goal of this machine is for me to be able to turn on my Xbox while seated on the couch and just throwing a roll of toilet paper.
Steps:
A: A roll of toilet paper is thrown by me to the ball.
B: Ball is hit from an inclined plane and rolls down the inclined plane
C: The ball strikes a book creating a domino effect of books
D: The books will knock over a weight which will hit one side of a lever
E: The lever will start the rotation of a fidget spinner
F: The fidget spinner will hit earbuds handing down which will cause them to swing
G: The swinging will cause them to knock down a small speaker which will knock down books in a domino effect
H: The domino effect will lead to the spin bike where a weight will push the pedal forward
I: The wheel will have a fishing rod attached to it and move forward
J: The forward movement of the rod will cause the Xbox to turn on and start my game
Types of simple machines used:
A. Inclined plane
D. Lever
H. and F. Wheel and axle
Types of energy being used:
- Chemical Energy: The chemical energy in this machine starts with me. I received chemical energy from the food I ate, and that energy allows me to throw the roll of toilet paper which starts my machine.
- Mechanical energy; Mechanical energy is the movement of an object from one place to another and so the toilet paper roll gets the energy from me and turns into mechanical energy as I throw it across to my machine.
- Gravitational energy: The gravitational energy happens once I throw my toilet paper roll and it strikes the stopper I placed. Without gravitational energy, the roll wouldn’t drop down and hit the soccer ball, but the gravitational energy allows it to drop down and hit the ball.
- Rotational kinetic energy: The rotational kinetic energy is once the soccer ball is struck, it will allow the ball to roll down the inclined plane.
- Kinetic energy: The kinetic energy would be the several domino effects that I had because a domino effect will convert gravitational potential energy into kinetic energy.
- Electrical energy: The electric energy in my machine would be once I turn my Xbox on, electricity flows through my Xbox to my tv allowing me to use the tv as a monitor of the Xbox.
- Sound energy: Near the end of my machine, once the fishing rod hits the button on my Xbox, there is sound energy produced because it makes a sound as it turns on.
Energy transformations:
- The first energy transformation is from the chemical energy within my body to throw the toilet paper hitting the ball which causes mechanical energy.
- The ball had potential energy as it sat on a higher level but then once it was struck, it got the mechanical energy and changed it into rotational kinetic energy as it rolled down the inclined plane.
- The rotational kinetic energy then becomes mechanical energy once again as it strikes the books converting their potential energy into mechanical energy.
- The movement of the fishing rod into the button on the Xbox will convert the mechanical energy into 2 different types of energy. First, it will create sound energy as the Xbox will make a sound as it turns on. Secondly, it will create electric energy which transfers from the Xbox to my television where I am then able to play my games.
Here is the core competency for my project:
