Which of the following is an example of a tool that operates according to the principles of the screw?

A corkscrew is a classic example of a tool that operates according to the principles of the screw. The design of a corkscrew features a helical thread wrapped around a central shaft. This spiral design allows the corkscrew to convert rotational motion into linear motion, enabling it to penetrate and lift out a cork from a bottle. The mechanical advantage offered by the screw's design makes it easier to exert force in a controlled manner, allowing for efficient extraction with minimal effort.

While other options are important tools in mechanics and everyday tasks, they don't demonstrate the working principle of the screw. A hammer operates through the principle of leverage, a pulley utilizes tension to lift loads, and a wheelbarrow functions primarily based on the wheel and axle principle for transporting materials. The corkscrew distinctly exemplifies how the helical design of a screw can facilitate movement and force application.
