The descriptions you've provided correspond to the following simple machines:
1. **Lever**: A rigid bar that is free to move around a fixed point called a fulcrum. Levers can be used to lift heavy loads with less effort.
2. **Inclined Plane**: A slanted surface along which a force moves an object to a different elevation. Inclined planes make it easier to lift objects by spreading the force required over a longer distance.
3. **Screw**: An inclined plane wrapped around a cylinder. Screws convert rotational motion into linear motion and are used to hold objects together or lift materials.
4. **Wedge**: A V-shaped object whose sides are two inclined planes sloped toward each other. Wedges are used to split, cut, or separate objects.
These simple machines help to reduce the amount of force needed to perform work by converting and redirecting force in various ways.
