Did you know that the most of the six simple machines were used in ancient times? As a matter of fact, all of them were. Before I tell you about that, I should introduce the names of all six simple machines. The six simple machines are incline plane, the wedge, the screw, the lever, the wheel and axel, and the pulley. I have chosen to research, the incline plane and the lever. Now I will tell you some more information on these two topics.
The first simple machine that I have chosen to research is the incline plane. The incline plane was used in ancient Egypt. The reason why this simple machine was used then was because the Egyptians used the incline plane or the ramp to help carry blocks while making pyramids. The ramp was a much easier way to carry blocks in this manner because of this example. If you had to carry something up a ladder, it would be much difficult than if you had to carry something up a ramp. With this example it would be much easier to give this simple machine a definition, so an incline plane is basically a sloped edge and one end is taller than the other. Another ample of this simple machine is a pyramid. Did you notice that it was sloped? It’s not really a machine used but it is an inclined plane other inclined planes ore door stops and roller coasters. They are either sloped or slanted and they are both used in various ways. If you do not quite understand this simple machine, I have a good example that might help you understand. Do you ever watch television and you see cars trying to do different tricks, when you see them jumping off of what they call a ramp, that is actually one of simple machines that is called a inclined plane. So now you know that the inclined plane isn’t only used now...

...and not even know that it was a lever. The next time you hold something, you should ask yourself if it is a lever and that should show you how common the lever really is.
In conclusion, the two simple machines that I have chosen to research which are the inclined plane and the lever have more usage than I thought. I knew that they were both used in ancient times but I am glad because I now know where they were used in ancient times and how they were used in ancient times. I now know more about the 6 simple machines then I did before. Even though my main focus was about the inclined plane ant the lever, when you look things up for topics like this, it is hard not to stop and look at the other related topics.

Early experiments with a ten-ton or heavier hollow ball being towed by a ship anchor linked to two very, heavy tractors, a device similar to one used in Australia, a one hundred ton tracked tank-like vehicle and the three wheeled LeTourneau tree-crusher all were unsuccessful. The parts were either too hard to fabricate or were too heavy to transport and the LeTourneau tree-crusher was too vulnerable of a target because of its large size (Evans). Success finally came when the Rome Plow was introduced.
Gears are one of the oldest equipment known to mankind. They can be traced back to The Chinese South-Pointing Chariot in the 27th century B.C created by Ma Jun a mechanical engineer. The earliest explanation of gears was that the “direction of rotation is reversed when one gear wheel drives another gear wheel”- Aristotle in the 4th century. As well as Greek engineers used gears in clocks and water wheels. (2010 Ronson Gears)Early gears were made from wood, they were used in wind to decrease and increase the rotational speed .Gear manufacturing and design rapidly developed through the nineteenth century.( 2014 eFunda, Inc.)
Wrought iron was a very popular material during the Industrial Revolution, but by the Second Industrial Revolution, steel had taken its place. Iron was then improved to be malleable and has been steel’s runner up ever since. Rubber and plastic were also created in this time frame, as scientists began to research macromolecular chemicals and synthetic materials. Electricity was still being explored during these years, as minor improvements were made increasing the quality and reliability while reducing the cost. One of the most important inventions to come out of the Second Industrial Revolution was the airplane. In 1903 the Wright brothers used their knowledge of mechanics and aerodynamics to create the first airplane, by 1914 the end of the Revolution the autopilot system was developed, and just thirty years after the Wright brother’s first flight, the first commercial airline business was created. Revolutionizing the system of production in agriculture had a slow start, because most of the work in agriculture was performed by human hands, such as tending to the crops or weeding. Once internal combustion engines were created they were applied to this problem. Right before WWI, tractors and combines began surfacing in the agriculture industry, changing it forever.
“This machine may be turned by water or with a horse, with the greatest ease, and one man and a horse will do more than fifty men with the old machine. It makes labor fifty times less, without throwing any class of people out of business.” - Eli Whitney, 1793
Over the years, transportation has come a long way. However, before the time of automobiles, there were just a few options for transportation such as the horse, horse and
Rube Goldberg Machines have a simple concept: a Rube Goldberg Machine is a series of complicated effects, often using simple machines, to accomplish a simple task, such as turning off the lights, or filling a cup. A Rube Goldberg is made up of many different simple machines. What are simple machines, and what do they
In the coarse of human existence, civilizations have made farming their primary source for food. As long as farming has been around, agricultural implements have been used to farm the land. Scientists believe that the first plows that were used, date back to 4,000 B.C. These plows were simply pointed sticks but nonetheless, they were the pioneers of modern day plows. By 3,000 B.C. the Egyptians invented a plow with a wider, triangular share that turned more dirt in a wider furrow. As the population grew over time, more and more people moved into Europe. The soil contained much more moisture, and required a lot of power to be able to pull plows through it. The Dutch then invented an iron- covered moldboard that cut much better through the earth and greatly reduced the power needed (Drache 2-3).
The simple machines we used are wheel and axle, 2 pulleys, multiple inclined plane, and a screw. The device progress’ through the following step: 1. A marble triggers a mousetrap, releasing a peg stuck on a peg board. 2. The peg detaches from the pegboard, releasing a marble. 3. The marble progresses down a marble run going through a wheel and axle. 4. The marble then drops down a small tube, encountering a screw in which it circles around. 5. The marble drops down another small tube, landing in a pulley in which the other end of the pulley goes up triggering a marble to be detached from a groove in a piece of wood. 6. The marble is triggered and rolls down a hot wheels ramp, down an incline plane with dowel rods guiding it in a zigzag motion eventually being tunneled into a wheel and axle with a detached ramp. 7. The ramp (or inclined plane) is pushed down (since it 's tied to a wheel and axle) by a marble which causes it to fall down onto another inclined plane. 8. The marble rolls down the hot wheel track guided in a zigzag motion. 9. The marble falls onto another ramp, rolls down the ramp and is slowed by a piece of tape.

...ntroduced. Tools in agriculture plays an important role, nothing could be done without tools. Better tools can be more efficient, such as iron plow; it is stronger than the wooden one and the usage were much longer. Also an “Englishman named Jethro Tull, who introduced an improved seed drill in 1701.”(Agriculture) The seed drill could sow seeds in a straight line, so the space between those seeds will be much likely equal and the plants could grow better.
Another major breakthrough in farming history is the invention of the tractor. Steam-powered tractors were being tried out as early as 1868 (Historical Timeline). However, they didn’t really take off until several years later. These tractors were monsters, usually weighing in at around 20,000 pounds or more. Some of these tractors had very high power outputs for their time. One example of this is the Case 150 horsepower steam traction engine that w...

So this essay will delve into the era of the 1880's and focus on one of the most important inventors that ever lived, Nikola Tesla. Many business machines were patented before Nikola Tesla patented the alternating-current "electromagnetic motor" in 1888 (while the popular Thomas Edison was stubbornly clinging to direct-current motors), but soon more and more inventors were realizing this new source of harnessed power could bring glorious miracles to business, thus providing them with even more glorious profits. But first, the washing machine, truly in honor of my great grandmother, who will be 105 years old this year.
This hopefully adds some insight into the use of electric motors, and the principals of them that make these motors work. Such as electromagnetism, binary switches for DC motors, and the selection of a running frequency of a motor through the use of an oscillator.
The fist computer, known as the abacus, was made of wood and parallel wires on which beads were strung. Arithmetic operations were performed when the beads were moved along the wire according to “programming” rules that had to be memorized by the user (Soma, 14). The second earliest computer, invented by Blaise Pascal in 1694, was a “digital calculating machine.” Pascal designed this first known digital computer to help his father, who was a tax collector. Pascal’s computer could only add numbers, and they had to be entered by turning dials (Soma, 32). It required a manual process like its ancestor, the abacus. Automation was introduced in the early 1800’s by a mathematics professor named Charles Babbage. He created an automatic calculation machine that was steam powered and stored up to 1000 50-digit numbers. Unlike its two earliest ancestors, Babbage’s invention was able to perform various operations. It relied on cards with holes punched in them, which are called “punch cards.” These cards carried out the programming and storing operations for the machine. Unluckily, Babbage’s creation flopped due to the lack of mechanical precision and the lack of demand for the product (Soma, 46). The machine could not operate efficiently because technology was t adequate to make the machine operate efficiently Computer interest dwindled for many years, and it wasn’t until the mid-1800’s that people became interested in them once again.
