These technologies make life easier for humans and help them carry out their daily activities. Machine technology around the world is mainly based on six simple machines. These are the lever, the inclined plane, the wedge, the screw, the wheel and axle and the pulley. These machines provide a mechanical advantage to people and allow them to work safer and less strenuous. From the Stone Age to the present, simple machines have had the greatest global impact because they help human beings create less work and effort, they have developed new technologies throughout history and they continue to help people create new technologies today. a science behind them that allows you to work with a fraction of the effort. According to the Lerner Publishing Group of the United States, "machines allow people to apply force and do more work than could be done with muscle power alone, and the force can be applied more efficiently" ( Woods 2). Work is equal to force times distance; therefore, when machines are used, they decrease the force or effort required to accomplish the job. The consequence is that people have to cover a greater distance when they reduce their effort. Whether people trade less force for more distance, or vice versa, they still endure the same amount of work. Simple machines also allow users to change the direction of force applied, which can also simplify the task. Western Michigan University states that the input force is equal to the work done in the machine and the output force is the work done by the machine (Wakild 4). A lever is a perfect example... middle of paper ... today's society. They are used to move around or hang a painting on the living room wall. They are also used during construction and are even used in a task as simple as turning on the kitchen sink. Without a doubt, the world would not be the same if simple machines did not exist. Simple machines have had and continue to have the greatest global impact because they create less effort for people, have helped people develop new technologies throughout history, and they continue to do so. to help people create new technologies today. Simple machines are basic technologies that represent major uses for the human race. They represent a huge benefit to people and will continue to be used in the future. Over time, people have become more mechanically intelligent through simple machines and they will continue to help the human race obtain new technologies to change the world..
