Answer:

A jackscrew functions as:

B. To adjust the position of an object

A jackscrew is a simple machine commonly used for lifting heavy loads or adjusting the position of objects. It consists of a screw that can be turned to move a plate or another piece of machinery. When the screw is turned, it moves the load up or down depending on the direction of rotation.

The screw in a jackscrew is connected to a plate that houses the load or to a piece of machinery that needs to be adjusted. By turning the screw, the user can precisely control the movement of the load or machinery, making it a versatile tool for various applications.

This basic principle of a jackscrew allows for the lifting of heavy objects with minimal effort, as the rotational force applied to the screw is converted into linear motion to move the load. Whether used for lifting vehicles, adjusting industrial equipment, or other purposes, the jackscrew is a reliable and effective tool in many settings.
