Answer:
A screw is another form of an inclined plane; it is simply an inclined plane wrapped around a rod, like a spiral. ... A screw is really just a cylinder with an inclined plane wrapped around it.
An inclined plane consists of a sloping plane and is used to raise heavy bodies. Inclined planes make it easier to lift objects to greater heights. There are two ways to raise an object: they can be either raised by lifting it straight up or by pushing it diagonally up.

There are two ways to raise an object: they can be either raised by lifting it straight up or by pushing it diagonally up.Lifting an object straight up moves the object in the shortest distance but a greater force must be exerted. Using an inclined plane to lift objects requires a smaller force but must be exerted over a long distance. A few everyday examples of inclined planes include sidewalk ramps, highway access ramps, inclined conveyor belts, and switchback roads.
