What is the simplest type of machine?
Simple machines are tools that make work easier. They use a force to do work, such as lifting or moving. There are six simple machines: lever, wheel and axle, inclined plane, wedge, screw, and pulley.
Simple Machines - the Building Blocks of Technology
Lever: A lever is a straight bar that turns around a fixed point called a fulcrum. Wheel and Axle: A wheel and axle is made of two circular objects of different sizes connected together. Inclined Plane: An inclined plane is a flat surface set at an angle.
Which simple machine do you think is the most useful?
- Inclined Plane
The lever was one of the first simple machines used by ancient civilizations. The wheel and axle is one of the most important inventions in history. The inclined plane can reduce the amount of force required to lift an object by half.
