Question

3. What is the advantage of a screw over a nail in keeping things?​

Answer 1

Explanation:

Screws provide a mechanical advantage. Driving in a screw takes less force expended over a greater period of time than driving a nail into the same material.

Answer 2

Answer:

A screw is better than nails as it holds the things better than a nail. This is due to the presence of threading in screws that grips the surrounding material tightly. Also screws are easier to control than nails and can be removed easily.
