Question

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

Answer 1

D. 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.

Answer 2

The answer is D. 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.
