Simple Machines

We had to create 4 simple machines and try to get the best Ima and percent effeciency that we could from those four machines.  We had to create the pulley, the inclined plane, the lever and the wheel and axel.  The objective was to put a box of nails on the machines and see which group  could get the highest amout of Ima and percent efficiency.

Inclined Plane (Jason Solomon)                                                   Wheel and axel (Joe Scotto)

My group came in dead last for almost every test except for one.  Our inclined plane was the only one that did not finish in last.  I was not there for most of the building and the testing.  So I was unable to accomplish much on any of these projects.   Noah's group came in first.  They ended up having the highest effiency and mechanical advantage. 

The measurments on our machines were not corrected and completely off.  This cause us not to get to much effeciency from our machines.  This caused them to not do as good as the other groups.  Our pulley also feel apart before the testing so we couldn't even see how well we had done on that.  If we were to do this again, we would need to do the measurments differently.  If we had gotten them correct it would have been a major differnece in our results.  I think with a little bit more practice we will be able to make simple machines to there full ability. 

Build a compound machine



For our machine we used our wheel and axel and our lever and combined them.  We did not have a pulley becuase it was destroyed in a tragic accident.  We hooked the lever up to the wheel and axel so that pulled the lever up.  We used this idea to try and get as much Ima as possible since we did not have a pulley. 

We had tested this compound machine twice.  The first we had gotten a score of 14 Ima.  Which would have been in the C range of our grading system.  We decided that if we used a smaller dial on the wheel and axel it would help the compound machine gain more Ima.  So we then did that and that lead to us getting up to 28 Ima which got us into the B+ range.  Our methods wored but not as well as others.  Another group ended up getting a Ima of 247.  Which was a lot better then ares.  One of our biggest problems was not having the pulley.  It could have increased out machine significantly.

The most difficult thing to grasp was how to inhance the Ima of our machine since we did not have the pulley.  I wasn't surprised by that much during the process of making the machine.  In future projects we can being more careful with our machines and make sure they don't fall apart.  If we are able to keep things together I believe we will do better.  We can use things such as using a smaller dial to create a greater Ima in later projects. 

Six Simple Machines

A) Six simple machines-Lever, Pulley, Wheel and axel, Wedge, screw, and incline plane.
B) We can reduce them to four because The wedge and the incline plane are very similar to each other.  They each have the same type of shape.  The pulley and the lever also because they both use force on each side.

Field Trip

Field trip

We should go o a field trip to a pumpkin throwing competition.  We could learn how people make their trebuchets.  We could get ideas for our final project.  We could learn how each person made their and the ideas they used to create it.  It would help us make ours better by possibly taking different ideas and combining them together.

Westwood on the cutting edge

It would be a great thing if we could 3d print toilets.  Or parts for the toilets.  We would not have worry about ordering parts we could just creat the parts we need to fix the issue.  The 3d printer would allow for these toilets and parts to be created with ease.  It would change the plumming world completley.   










Brain storming:
3d printed toilets- You can create toilets or toilet pieces to help fix or give youself a new toilet.
Artifcial human body parts- You can create human body parts from the 3D printer so if you lost a body part you can print one out, so you can have a new body part. 
 3d printer- I will create a 3d printer out of my 3D printer so i can sell them and make more money
3d Mr. Atkins- I will create it so we can recreate Mr. Atkins so he will be back in class(my idea not Jasons)
Muzzle- I will create a muzzle so when jason talks about fantasy football in class we can put it on him so we won't be able to hear him

Design Cycle Notecard challange

   
We were given a 5x7 notebook and tape to make paper colums.  These colums were to hold as much weight as you could get them to.  The best way to make the colums was to make them short and that the center was a hole with no loose paper.  Cause the longer the colum the more likley that it would fall or buckle under the weight.  You also want to make sure that it is not to skinny as well.  Long and skinny is the wrong way to go.  The best way was to make it wide, but not to wide, and at leat one inch tall. 

The self driving car

Google has recently been able to develop the technology to create a self driving car. The cars use video cameras, radar sensors and a laser range finder to see other traffic.  As well as detailed maps to navigate the road. 
The self driving car is not yet ready to be purchased.  It is a huge advancement though.  It allows people to not have full control of the vehicle which could be a good thing, because there won't be human error.  It is a huge advancements then what cars do now.  This is historically important because it will help cut out a lot of accidents that may happen with a human driver.  

The Toilet

The toilet is one of the best invention to be created.  Even though Thomas crapper has been known as the inventor of the toilet, there has been a few others who have tried to create and may have created a functioning toilet.  The toilet can be traced back to 1596 by a British nobleman, John harrigton.  Thomas had the first patent for the toilet. holds the 1819 British Patent for a “Silent Valveless Water Waste Preventer”. This device was a system which allowed a toilet to flush effectively

The toilet helped allow for indoor plumbing.  People no longer had to go in holes or things like that.  This product help everyone.  A flusing toilet help keep things sanitaary as well.  It was not just lying around in a hole now.
