What are Screws and wedges modified as?

Screws and wedges are modified as simple machines that convert force and motion in useful ways. A screw is essentially an inclined plane wrapped around a cylinder, which allows for the application of a smaller force over a longer distance to lift or hold heavy objects. A wedge, on the other hand, is a triangular-shaped tool that converts a force applied to its blunt end into a splitting or lifting motion, often used for cutting or separating materials. Both tools exemplify how mechanical advantage can be achieved through shape and design.
