how did screws influence history and how might it influence the future?

Question

give me some ideas please, tx its for a 1page report on science

Answer 1

This is an intriguing question.

When one thinks of the screw and how it works you need to recognize the mechanical advantage of the inclined plane. We all know it is more difficult to walk uphill than on a level but if the incline is made to resemble a small rise rather than a steep hill or mountain the amount of effort you will need to reach the top will be far easier on your legs. So when you get right down to it this is all the screw does: it lessens the incline and thus takes less effort. This is the mechanical advantage.

The Great Pyramids of Egypt constructed thousands of years before Christ used this principle to muscle the large stone blocks along paths winding around the sides up to the top. In Roman times water pumps for irrigation used a wooden rotating auger inside a wooden cylinder to raise water below to the level of the fields. So the screw principle was well known in Antiquity.

Getting back to the threaded metal screws or nuts and bolts we see today: these are just the same ideas that the Egyptians were using but reworked in metal and on a smaller scale. As the understanding of mineralogy and mettalurgy progressed from the Industrial Revolution to the 19th and 20th centuries we learned how to mix metals to assume desirable characteristics and how to harden these alloys into something far more usable and durable than wood or stone.

At the heart of all of the computer controlled machines used in the metals industry that require precise and repeatable movements you will find drive screws transferring the power of electricity to do the heavy work. If an idea can be drawn, these machines can make it happen so the sky is the limit. The screw is as fundamental to modern society as the pencil is to paper.

Good luck with your research. Live long and prosper!

Answer 2

A 'screw' is how one gets water from a lower level to a higher level - and thus they allow fields that are above water level to be irrigated.

That should be enough for you to run with...

Answer 3

Screws, do you mean like nuts and bolts.
Or do you mean Jail Officers who are
sometime referred to as " Screws ".

Oh, ok you typed " it ".

Sorry, Screw inside slang term.

Answer 4

you mean the 'verb' or the 'noun' part of it?
