The tool, which helps the people to execute a task, is explained on Facts about Machines. A machine will be able to conduct an action if it has the source of power. The electrical, thermal, motorized or chemical means can provide the energy for a particular machine. To make a tool categorized as a machine, it should own moving parts. The power tools without moving parts are also present today due to the development of electronics. Let us find out other interesting facts about machine below:
Facts about Machines 1: the complex machines
