How is a screw and an inclined plane related? What are some examples of them?
Do the following activity:
Take a piece of paper and cut out a right-angled triangle from it.
Darken the hypotenuse of the triangle so that it is distinctly visible.
Now, take a circular pencil and wrap the triangle around it such that the darkened edge forms a spiral around the pencil.
The triangle’s darkened edge is basically an inclined plane and this activity shows that a screw is basically an inclined plane wrapped around a cylinder.
A real world application of such a mechanism is the bottle type screw jack, where the rotation of the screw raises a platform. This simple machine is used to change damaged/punctured tires on a vehicle by raising it safely. It accomplishes this by having a high friction angle, allowing loads to be raised with minimal effort and not slip back down without the explicit effort of the user.
