An inclined plane is a fundamental simple machine that can be used to create two other simple machines: the wedge and the screw. A wedge consists of two inclined planes joined together, allowing it to split or lift objects, while a screw is essentially an inclined plane wrapped around a cylinder, which converts rotational motion into linear motion for fastening or lifting. Both utilize the principles of the inclined plane to reduce the amount of force needed to perform work.

A screw is not typically considered the least efficient simple machine; rather, it is often viewed as one of the more efficient tools for converting rotational force into linear motion. Its efficiency comes from its ability to amplify force while requiring less input effort over a longer distance. However, the efficiency can vary based on factors like the angle of the threads and the material used. In general, each simple machine has its own specific applications and efficiencies based on design and use.

Scissors are considered a type of lever, which is one of the six simple machines. Specifically, they function as a first-class lever, where the fulcrum is located between the input force (the handles) and the output force (the cutting edges). When you squeeze the handles together, the blades move closer, allowing them to cut through materials. This mechanical advantage makes cutting easier than applying direct force with your hands.

A wheelbarrow is considered a compound machine because it combines multiple simple machines to facilitate lifting and moving heavy loads.
