Question

The threads of a screw are an inclined plane wrapped around a post. How does a screw make the work of fastening two objects together easier?

A. The screw changes the direction of a force - it converts linear force into rotational force. It also reduces the force required - the closer the threads, the smaller the input force required to get the same output force.

B.
The screw changes the direction of a force - it converts linear force into rotational force. It also reduces the force required - the closer the threads, the larger the input force required to get the same output force.
