Cách sử dụng
A lever is a simple tool that can be used to lift or move heavy objects. It is usually a long bar that is supported by a fulcrum or pivot point. One end of the lever is known as the effort or input, and the other end is the load or output. To use a lever, you apply force to the effort end, which then causes the load end to move. Levers can be found in many different contexts, from simple machines like door handles and see-saws to more complex machinery in factories and construction sites. Understanding how to use a lever effectively can make work easier and more efficient.
