Simple machines are devices with no, or very few, moving parts that make work easier. Examples: i. The lever consists of a long beam and a fulcrum, or pivot. The mechanical advantage of the lever depends on the ratio of the lengths of the beam on either side of the fulcrum. ii. The inclined plane is simply a flat surface raised at an angle, like a ramp. iii. A screw is essentially a long incline plane wrapped around a shaft.
