Simple machines are six basic mechanical devices defined by Renaissance scientists. In essence, they are elementary mechanisms that amplify the force you use to move objects. For example, a lever multiplies the force you use to push one of its ends to lift the other (loaded) end. Many other, more complicated machines are created by putting ...
