How does a screw make life easier?

Answer 1

A screw converts rotational force into linear force, or vice versa. A screw jack, for example, converts the rotational force of a hand lever, or a motor, that rotates around a centre pivot point, into a linear force that extends or retracts a threaded rod. The rod can be used to lift a car, open a flap, or steer a wheel.

.

Another example of a screw is the Archimedes Screw, in which a long screw propeller encased in a tube. The Archimedes Screw lifts, or pumps, a fluid, such as water, through the tube to a higher location.

.

A carpenter's screw uses its threads to bind objects (often pieces of wood) together. As the carpenter turns the screw, it forces the threaded shaft to drive deeper into the wood until it becomes tightly affixed.

.

These examples make life easier because, in the case of a jack, people are not strong enough to lift a car, but with the aid of a screw jack, a single person can crank the jack handle and thus lift the car (or part of the car) off the ground. An Archimedes Screw made life easier, as it was the first known example of a mechanical pump that lifted fluid from one level to a higher level. The carpenter's screw makes life easier because a screw will hold pieces of wood together stronger and more securely than a nail will, and unlike most nails, a screw can be easily reversed out of the wood.
It holds things together better than a nail.

Answer 2

A screw is a small device that is made up of 2 wedges. it helps make things get buld faster. the first screw was sold by jhonny hogal who lived in jamacia. then more and more poeple made screws. i hope dis helps u. thankyou

For one, they are extremely stable, and do not slip out because the grooves on the screw allow it to hook into the wall, and cannot be removed by tugging at it, whereas a nail would easily slide out. Plus, screws hold the components of just about everything you see together so they function properly and don't fall apart - including the monitor you are looking at. Without screws, pretty much everything you see would not exist because it wouldn't be able to hold together. And since everything you see makes your life easier in some way, that is how screws make life easier.
