A simple machine with a wedge at one end, an inclined plane wrapped around an axle in the middle, and a wheel at the other end is a -----?

The simple machine you are describing is called a screw. A screw is a device that converts rotational motion into linear motion. It consists of a cylindrical shaft called an axle, which has an inclined plane wrapped around it called the thread, and a wheel at one end to provide a grip for rotating the screw.

To find the answer to your question, you can learn about simple machines and their characteristics. Simple machines are basic mechanical devices that make work easier by either changing the direction or magnitude of a force. They are often categorized into six main types: lever, pulley, wheel and axle, inclined plane, wedge, and screw.

By understanding the characteristics and functions of each simple machine, you can identify the correct name for a particular combination of these elements. In this case, the combination of a wedge, inclined plane, and wheel indicates that the machine you're referring to is a screw.
