Simple Machines

 

 

 

Inclined plane

Summary

 

In this project our goal was to build 4 simple machines to learn how to get a specific mechanical advantage. After we built these machines we tested them to see whose team would be the closest to the ideal mechanical advantage. Then from the data we collected we the percent efficiency and from that we calculated the average percent efficiency.

1. Group 1, Rep. Matt

 

2. Group 2, Rep. Ricky

 

3. Group 3, Rep. Phil

                                                               

4. Group 4, Rep. Jason

 

5. Group 5, Rep. Robert

 

6. Group 6, Rep. Chris

                                                                          It was difficult to pick a winner since every team unitentionally "cheated" to get a specific mechanical advantage.

Analysis

Our group didn't get 100% efficiency because human error and lack of calculations led to problems that altered the IMA for the machines. For example even though our teams pulley got 90% efficiency, since we put the handle to pull the lift so far out on the circle it was glued on it gave us a unfair advantage. If I could do anything differently  I would most likely go back to the projects and calculate the proper areas where we should put parts or the weight.



Wheel and Axle

 



Simple Machines Do Now

• Screw
• Inclined Plane
• Wedge
• Lever
• Pully
• Wheel and axle

• we can reduce 6 simple machines into 4 simple machines by noticing tha the screw has wedges along its length. Also wedges must have a point where to sides converge so when those sides meet that creates a inclined plane.

Notecard Challenge

Our columns were 1' x 1/2'


Summery

What we did was we built cylinders from notecards and 4' of tape. How we started was we brainstormed and sketched the placements and thicknesses of the columns. Then Dylan and I did was we had a ruler and measured 1' and drew a line to mark 1' and we made seven of these lines. From these lines we made 7 columns holding them together with tape, but before we put the tape to hold them together I measured if they were at least a 1/2' wide. After we finished building our first set of columns we tested them and during testing we put two 45 lb weights on top of our columns then started stacking books. In the end we lifted about 209 lbs. A few days later we made a new set of colemns for the Atkins A, but we tried to make them more cylindrical this tme. Saddly the columns failed. They most likely failed due to them being slighly too wide or thin and possibly not flat on the tops and bottoms. 

                                 Analysis

In our structure both of our attempts both failed not by the typical overturning, but crushing. In our first attempt when the columns failed only a few actually were crushed while some still were standing and holding there weight. the other attempt for the Atkins A instantly crushed them. The columns became flat which proves that it was crushed and not overturned.
If I had different materials; (1) 5 x 7 notecard, (2) 8.5 x 11 pieces of copy paper, and 8 inches of tape I would wrap the columns made from the notecard with the copy paper to support the columns and wrap that in tape.

Research

 

Emotiv Insight:

The Emotiv Insight is a wireless headset that connects to an app on your phone and the headset reads your brainwaves to do commands. For example the headset can see your focus on a certain subject and seds the data to the app and you can see the amount of focus you had on it.

 

Raspberry Pi:

The Raspberry Pi is a credit card sized computer which can do anything a normal computor can do. It can download things and run programs. What the business that is making this hopes to do is to use the computer to help kids learn how to program.

 

Arduino Intel Galileo:

This is a circuit board that can be used to test prototypes. For example people can test LED's responding to social media or projects on home automation.

 

Makerbot Digitilizer:

The Makerbot printer is a 3D printer able to take digital models and use a plastic medium to build the model.

 

     Brainstorm

 

 

Using the Makerbot Digitilizer

 

 

1. We can use this as a way to layout things we are building. We can use it before we design something or during. For example we design a table and download it to the makerbot's program and make the printer print out a model of the table before we build it. This idea is especially good because these miniature models can show flaws in the design before you build the real thing to find the larger flaws.

 

 

 

List of other ideas:

1. We can use the arduino by creating a motor which can be used to motorize the joint on the catapults later in the year.

 

2. We can use the makerbot printer to make puzzles

 

3. We can use the raspberry pi to download music and creat a playlist for the class.

 

4. We can use the Emotiv Insight to read everyones brainwaves.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 





Guggenheim Field Trip

The Guggenheim Museum

 

 

 

 

The reason i chose the Guggenheim Museum of art is because it was created by a world renown architect. Frank Lloyd designed this building in a very odd shape, in the shape of a spiral. the exibits are shown along the spiral then break off into a cone shaped building.

 

I think  this place would be academically relevent because the building shows the limits of how architects can design buildings. It would also be educational because it was built by a world renown architect.

 

 



The Airplane Innovation

Robert Sitbon


The plane has changed the way society views the ways of travel worldwide. The modern version of the plane is very different than the plane that the Wright Brothers had. These planes have developed into massive beasts of the air. These planes have become mobile hotels with food and catering, they even let you watch television so long trips dont feel so long.

The most impactful part of innovating planes is the engine. The engines being changed over the years have made travel faster and more silent. The engines are also more fuel efficient using less diesel for long distance travel. Some planes have become gigantic for example some have enlared fronts to alow a larger lounge area for first class.

The Airplane Invention

Robert Sitbon
Author: The Wright Brothers
Date of completion: 1903
Name of work: Flyer

The Airplane

 

In 1899, the Wright Brothers get information from the Smithsonian about flight experiments. From the data they designed the first aircraft. Their design was a small, bipedal glider that was flown like a kite. While designing the aircraft they faced the hardest problem, controlling it during flight. After many failed and sucessful attempts they found that a moveable tail would fix the controling problem. They then studied how to use a propeller and placed one on their aircraft known as the "Flyer." on December 17, 1903 the Wright brothers took the "Flyer" ot to a custom made ari field and rode it down a hill, and after 2 attempts Orville Wright sustaied 12 seconds of flight. 

 

This invention was important to modern day life because it started a new way to travel. It lead to the creation and developement of larger and faster planes. These planes gave the power to us to travel accross the world instead of us having to use boats or ferries to travel.
