The Best Things Can Be Simple

For thousands of years simple machines have been an important part of life. They are found everywhere and in some places that you wouldn’t even think of. For example, if simple machines didn’t exist then we wouldn’t be able to move our arms and legs, because our joints are simple machines. From being an uncommon discovery to a common necessity, they are now used every single day. Whether we use them in schools, businesses, outside on the street, or even in space they make spectacular things possible. They are objects that have their own specific type of math, for example “mechanical advantage, if you want to find the force it takes to lift an object, let’s say with a lever, you take the force it takes without the machine divided by the force it takes with the machine and that’s the mechanical advantage” (St. Andre 127). Another “important mathematical factor of simple machines is Work” (Working with Simple Machines ), every simple machine that moves an object, like a pulley has work, that is found by taking the force of the object multiplied by the distance the object moves. Putting the math aside, the main goal of simple machines are to help make life easier and to let people finish everyday tasks, which without would be very difficult. By looking at the history of simple machines it is easy to see that the early simple machines lead to the creation of more advanced simple machines. From the pulley to self reproducing machines, there is no telling what could be thought of next. The world is full of simple machines. There are 6 original simple machines in total, the lever, pulley, wedge, screw, wheel and axle, and the inclined plane. Each one has its own specific use, but these machines can work together, or alone. Some simple machines do not have to use any electricity, while some can use engines or motors to work. And, some do not even have parts that move
