Specific Physics

Earlier I posted about the different physics aspects that I planned on including. In this post, I will be giving specifics and revising a few things that ended up being changed. There are many examples for some of these, so I just listed a few.
  1. Different Forces
    • As the marble rolls down the pipe and as the train rolls down the track, frictional force is in action.
    • When the baseball is dropped on the lever, when the marble is dropped on the train, and as the dominos are falling on each other, gravitational force is in action.
    • when the marble is spinning around the loop, centripetal force is in action.
    • When the first marble hits the second marble and when the car hits the book which hits the ball, they are transferring momentum.
    • When the small magnet is attracted to the small magnet, magnetic force is in action.
  2. Different Simple Machines
    • The seesaw at the very end that caused the coin to fly up was a first class lever.
    • The train and the car both contained a wheel and axle.
    • The car drove down an incline plane. The train drove down an incline plane. The marble rolled down an incline plane.
  3. Pendulum
    • I ended up using only one pendulum. It was in the middle of the machine. A domino fell on it, causing it to swing.
  4. Transfer of Energy
    • When the first marble hit the second marble, the first marble transferred its kinetic energy to the second marble. The first marble now had potential energy. The second marble, which had originally had potential energy, now had kinetic energy. So, the first marble transferred its energy to potential energy and the second marble converted its energy to kinetic energy.
    • When the marble hit the train, the marble continued moving. It kept its kinetic energy. However, the train, which had been stationary, converted its potential energy into kinetic energy.

Completed Project!

Here is the video of my completed project.

In order to relate the machine more to Edgar Allan Poe, I decided to add a twist referencing Poe's short story "The Black Cat." Because my machine ends up flipping a coin, I decided that if the coin landed on heads, the cat dies… If it is tails, the cat lives…


Here are some in-progress pictures of the construction process:

I started with all of my materials in a pile in a basket.
Then, I  placed a pendulum at the beginning to hit a marble, but after testing this and being unable to make the pendulum function properly, I moved it somewhere else

I set a train underneath the structure so that the marble would hit it, causing it to roll down the inclined plane.

I originally set it up like this, but I was having difficulty manipulating the placement of the blocks and the pendulum, so I ended up revising it later.

I moved the pendulum here, where a tower of blocks would fall on a few dominos, hitting the pendulum, causing it to swing into some more dominos.

This is a complete view of the first seven steps.

This is a complete view of the final five steps.

This is a complete view of the final few steps from a different angle.

This is what it looks like after the machine was run.

Physics Involved

I plan on including many aspects of physics into my Edgar Allan Poe Machine. For example:

  1. Different Forces
    • frictional force
    • gravitational force
    • centripetal force
    • force of momentum
    • force of tension 
    • force of magnetism
  2. Different Simple Machines
    • lever
    • wheel and axle
    • inclined plane
  3. Height
    • At the end, the lever will raise the coin over 35 cm
    • The Machine starts above 35 cm
  4. Pendulum
    • A pendulum will be swung at the very beginning manually, beginning the chain reaction
    • in the middle, the tower will fall on a pendulum, causing it to swing
I will be giving the specifics when I complete the building process.

The Blueprint

This is my blueprint for how I plan on constructing my Edgar Allan Poe Machine. It is subject to changes if necessary, but it should help me get a general idea on how to put it together. Take a look!
