1) An inclined plane, wedge, and screw are examples of simple machines that allow a smaller input force to produce a larger output force through mechanical advantage.
2) An inclined plane is a flat, sloped surface that allows exerting force over a longer distance, reducing the needed input force. The mechanical advantage is the length of the incline divided by its height.
3) A wedge is like an inclined plane that can move, using force to split objects like wood. Its mechanical advantage depends on its length and width.
4) A screw is an inclined plane wrapped around a cylinder, with threads that act as an inclined plane to increase the distance force is applied for fastening. Closer threads mean
