Simple Machines



In the simple machines project, we made four different machines that complete four different tasks. All of these machines had one task in common, they were supposed to make it easier to pull a weight on it. we did this because we wanted to see how we can make things esier with machines that we make in the beginning. first we built the machine to have an effective machanical advantage. then, we marked where the weight would go or where Mr. Adkins would be pulling from (depending on what machine) lastly, we tested the machines to see which ones were effective and which were not. then we calculated the percent efficiency of the machines to see how well they did. 

This is the LEVER. Jack and I worked on this.

This is the INCLINED PLANE. Jack and I worked on it.














 



This is the WHEEL AND AXEL. Jack and I built it.
 
This is the PULLEY. me and Jack built most of it. Tyler helped with the wheels.

 

Out of the six groups, me, Jack, and Tyler placed 2nd place overall, while Rob's group placed 1st overall. for the pulley, we placed last, with Matt's group at -43%, because of our second attached wheel. Rob's group placed 1st in this. nobody else was able to qualify for this challenge. for the wheel and axel, my group placed 5th. the 1st place group was Rob's group. for the inclined plane, we placed last for it, because of the steepness of our's. Ricky's group got 1st for the inclined plane. Lastly, for the lever, we placed 2nd. 1st place was Rob's group again.

 

My group didn't reach 100% efficiency. I think this was because of our inclined plane being so steep and our wheel and axel not having the piece to turn it in the right spot. for the pulley, our second wheel was attached, meaning that the length of the string wasn't reduced making it harder to pull on the pulley. If my group could go back and redo the machines or fix them, first I would make the second pulley wheel hang free. then, I would put the piece of the wheel and axel in a better spot to help it turn for a better mechanical advantage. for the lever, I would make better markings to put the nails closer to the center and to pull down on the opposite side on the very end. Lastly, I would make a much less steeper inclined plane, to pull it a lot more easily. overall, I think my group did well.

6 simple machines do now

6 Simple Machines

 

 

PART 1

Lever

Wedge

Pulley

Inclined Plane

Wheel and Axel

Screw

 

 

PART 2

We can put the screws and the wheel and axel together to make them one. we could also put the Wedge and the Inclined Plane together to make them one. this would leave 4 simple machines left.

Westwood on the Cutting Edge

      My project is to print out airplane parts using a 3D printer. we would put it together and fly it outside. this project would work by designing the plane to make it able to fly, then print out patrs to be assembled. then when everyone has their planes, we can fly it outside and see who's goes the farthest.

Students can learm a lot from doing this project. they can learn how to 3 dimensionally print something out. they can also learn how a plane works if they didn't know already. Physics, math, science all will be incorperated into this project. Fabrication will also be a part of this. we would learn so much from printing, designing, and physics.

Other Possible Projects

3D printer

The 3D printer can be used for many affordable ideas. it is only $2000 for a 3D printer. 1 project we can use from this is redo the notecard challenge with this. we can create even colums with one colum, and print more of it.

We can print our own rocket engine. NASA is doing this and i think we can too bu on a smaller scale to make it affortable.

We could print out our own mini plane to fly outside. it would be affortable ande fun to do.

We should print out our own cars. this could work because if we first print wheels, we then print the body of the car and attach it to the wheels, then drive it in the parking lot.

We should try to print out our own food. it would be creative and experimental. we could make different kinds of food that we could eat in class.

Notecard Design Cycle Challenge

Design Cycle

      During this project, we had to use the design cycle to build some sort of way to support over 200 pounds with a notecard. this required us to think hard, wether it was about how to make our colums or where to put the colums under the weight as part of the layout. we also had to choose how many colums we made which became a major factor. my group got the "Atkins A" because of the way I designed the colums to have a line down the center for extra support. we failed to get the "A" many times but as this happened, we discovered the flaws we had in our design. we could then use these faults to deside how we can make it better.
      Many of my groups's designs failed due to crushing, buckling, and overturning. crushing is when the colum is too wide and can't support the weight, buckling is when the colums are uneven or too skinny, and overturning is when the colums fell over due to poor placement. we had to think of a better way to make sure that this didn't happen. overturning was the most common way that most of my classmates failed to get the "Atkins A". to prevent this, we hat to find a way to place the colums so that they were in the perfect place so that it could support the weight.

Pumpkin Chunkin

         I think that our class should go pumpkin chunkin. It would be fun and educational. in 21 days, at Royal Farms off of Sussex Highway in Bridgeville, DE 19933, there is a pumpkin chunkin event that would be great to visit and watch. it is an event each year, with innovative engineering and science-based ideas.
         This would be relevant to our engineering class. this is relevant because it combines catapulting something into the air, building a machine to do that, and problem solving like we do in this class. it incorporates teamwork, innovation and invention, creativity, and engenuity. that is why it is the best field trip for this class.

Innovation: Back up car camera

Back up camera
created by: unknown
February 2010

the back up camera is a life saving innovation of today. prior to the back up camera, people would turn around in their seat, which many still do, but also look at the mirrors. the mirrors don't always do the 100% job of giving people a full view of behind the car. this can prevent accidents, backing over people, and hitting other objecks. by December of 2010, people were urged to build all cars with these cameras because of their success. this is historically important because now people are more aware and less nervouse about backing up now.

 

Invention: the Telephone

Alaxander Graham Bell

The Telephone

 

     the telephone was created by Alaxander Graham Bell in 1875. prior to the phone, people would send letters and meet them in person to talk with one another. with the phone invented, people didn't have to do that, now they could speak on the phone from their home or payphone. this would have a huge impact on the world.

 

      the telephone was a device that would take a sound or a humans voice, and converts it to an electrical impulse which could be sent to another phone to be converted back to the original voice or sound. it became historically important because it gained popularity over many years. people used telephones often and it eventually became so popular that almost half of America's population used telephones by 1920. the telephone would create many room for improvement and opportunity for innovation for the future.

Maker Faire Info

Come to the Maker Fair 2013 in queens, New York. The fair is where engineers come together to show off creations and share ideas. It is on September 21^st. It goes on 10:00 Am to 7 Pm.

 

          The Maker Faire is the coolest place to see all fun types of inventions and gadgets. There is 3D printing, robots, transportation inventions, lasers, and more! The Maker Faire is for every one of all ages who love engineering. You will be able to check out other people’s inventions or show off your own. Come to the Maker Fair for a low cost of $30 for adults, $15 for the youth. My three favorite inventions of the Faire is the skateboard on treads, Miter tesla coils, and the Aero-quad.
