Mechanical tools are devices that help people perform tasks by using physical force or motion. They can be simple, like a hammer or screwdriver, or more complex, like wrenches and pulleys. These tools often make work easier and more efficient, allowing users to apply strength or precision in various activities, such as construction or repair. Many mechanical tools are designed to work with human power, while others may be powered by electricity or other energy sources. Common examples include drills, saws, and lathes. Each tool serves a specific purpose, helping users accomplish tasks that would be difficult or impossible to do by hand alone.
