The 6 Simple Machines
There are six different types of simple machines, and all of them are important because they each do different things. For example, levers provide leverage, and screws can amplify force. However, with all their differences, each simple machine is made for the same reason, to be the building blocks of machines. This is critical for our world since machines are made to make things easier. The world would be less efficient is we didn’t have machines, and without simple machines, we wouldn’t have them. That is why simple machines are important.
The first simple machine is a lever. A lever is a beam or rod hinging on a fulcrum. Most levers look like a line with one part connected to a triangle. As aforementioned, levers provide leverage, which in other words means boosting an input force to get a bigger output force. It consists of three things: a fulcrum (a fixed hinge), the resistance force (the output force), and the effort force (the input force). There are three different types of levers: Class 1 Levers, Class 2 Levers, and Class 3 Levers. The first one has the fulcrum in the middle, the second one has the resistance in the middle, and the third has the effort force in the middle. An interesting fact about levers is they were even used in ancient Egypt to move obelisks, which shows how helpful they have been through the ages. Below is a picture of a lever:
The second simple machine is a wheel and axle. The wheel and axle usually consists of a wheel, which is a round disk that rotates, and an axle, a shaft of which the wheel rotates around. It is used to lift weights, and is actually just a lever with the load applied to the perimeter of the wheel and axle, which are carefully balanced on the fulcrum. W...

... is a thin, twisted inclined plane that uses rotational motions to amplify force. For instance, a nail is a perfect example of a screw. Most common screws are circled in many ridges, also called threads. These will look like a metal cylinder with wire wrapped around it with a bit of space between each coil. Although screws are important, they are sometimes not very efficient. Most of the energy from the screw turning is lost in sliding friction energy between the object and the screw. Even if the screw is very well made and lubricated, it might only have from 10-20 percent of actual efficiency. Some more examples of screws are threaded lids, drills, or corkscrews. The history of the screw dates back to the times of ancient Greek. Apparently, Archimedes created the screw press, which has never been found but has been drawn and painted. Below is a picture of a screw.
...icycles, and heavy duty industrial machines all rely on common gears, and without different types of gears we wouldn’t be able to live in the modern society that is today. We know how they've helped us build modern civilization; it'll be exciting to see what they help us accomplish in the future.
Simplicity is defined in the Merriam-Webster online dictionary as a simple state or quality; freedom from complexity; absence of elegance and luxury; uncomplicated. In the world today, many people think that an iphone or computer watch may make their world simple, but these technologies only make the world we live in more complex. Somehow there is confusion between simple and easy. It is most certainly easier to phone someone from your car rather than pulling over to a pay phone and getting out a quarter. It is also easier to put a letter in the fax machine rather than addressing an envelope and putting a stamp on it and walking it to the mailbox. These two instances that have been described are, in fact, easier, but not simpler. Simple is not having to figure out how to use the cell phone or fax machine and, at the same time, having these two items cluttering our space. Fewer people communicate through cards and letters now because we have e-mail and fewer people go to the library because we have the Internet. These are great items and they may make life easier, but not simpler.
The evolvement of technology from in the past to today has changed drastically. There are things that people used to do for jobs that they can not do because of the evolution of machinery. These machines do exactly the same thing as what the worker would do but in only half the time. These evolutions of technology are not just with machinery; it has also evolved in other areas such as electrical, chemical, and other physical forces. These tools of machinery that society uses has only happened because of the growth of scientific principles. People learn a lot about these tools and try to find ways to improve them. The study and understanding of these tools increases control by humans over labor processes by means of machines and machine systems.
In this book, Forster is able to portray a reality that could become true if we, human beings, keep depending on technology for survival. Although it is very distressing that people became dependable to the Machine to the extent where they loose their humanity and become like a machine as well, with no mind of their own. It is incredible how people were not able to survive when the Machine stopped working; it is understandable that people nowadays will also have a hard time surviving without technology since we were born into a technological world. But the World will be well when people like Kuno remind humans what is really important in life.
Throughout the Industrial Revolution in 1780 there were many positive and negative effects that resulted during this time including technologies were improving, machinery that was making travel, luxuries and comfort better, and poor working/ living conditions. The Industrial Revolution was when societies in Europe and America started invent machines, which made manufacturing of products quicker, easier, and cheaper. Before all these machines in factories were created, the economy was all based on farming and peoples abilities to make products to sell. The Industrial Revolution began in Great Britain in the 1780’s and to Western Europe and the United States throughout the 18th Century. It began in Great Britain because there was good weather

An electric motor is a device used to convert electric energy into rotational kinetic energy. There are two different types of electric motors, and each has there own use. The different types are direct current and alternating current motors. Each of these motors will be analyzed in the following.
Gears, also known as cogs, sprockets, ratchets have existed since the invention of rotating machinery, providing machines with constant mechanical advantages increasing torque or speed of the shaft. Some of the fist gears developed were wooden pegs fitting onto slots. These setups were often greased with animal fat or wax to allow smooth operation.
When people think of robots, an image of a mechanical, stiff, talking, moving, human-like machine might come to mind. Robots are, in fact, computerized machines that are ultimately utilized to simplify larger scale tasks. They include control machines, computer controllers, or microprocessor based automated systems just to name a few. The ultimate goal of industrial engineering is to expedite processes; therefore, with such developed and modern technology, the manufacturing process is more efficient, cost effective, and there is almost no human error. With all its benefits the automation and robotics movement has made way for new fetes and greater prospects in economic terms for large-scale firms.
Technology has been growing throughout the years, always changing and evolving in all new ways. It has become almost a second nature to us by now, to use technology on anything and everything. We use technology for the smallest things, such as looking up the recipe for your next meal, or the name of an actor, or just to check up on a friend. It seems to be that the more technology develops, the more addicted and the more dependent we become. If one were to analyze and really think about how many times we use technology a day, we will start to realize how much it has consumed us. Just think about how many times a day you see someone on their phone, or on a computer. You will start to realize how addicted we are. It’s so common for us to use and see people use technology, that we take it for granted and never think twice about it. However, is becoming this dependent on technology a bad thing? I feel as though we depend a lot on technology
The pulley, lever, and and wheel, although simple ideas, have a modern definition of engineering.
Throughout time, machines, no matter how simple or complex, have played a vital role in the development of civilization into the future. In other words, machines have played a part into helping our culture develop into what it has become today. This dates back to the beginning of time when early man used a stick and a fulcrum (rock) to make a simple lever.
Each of the six basic styles of robot used in industry today were designed with different applications in mind. Some of the robots were designed for assembly, others are more suited for simple pick and place applications, while a select few are capable of carrying heavy loads over a large area.
Electrical motors function by converting electrical energy into mechanical energy by using the energy stored in the magnetic field (Sarma, 1981). The mechanical energy (torque) is produced when opposing magnetic fields try to lineup. Therefore, the center line of the north pole of a magnetic field is directly opposite to the centerline of the south pole from another magnetic field (Fitzgerald et al., 1981). The opposing magnetic fields in a motor are generated by two separate concentrically oriented components, the stator and a rotor (Figure 2-5).
