How are inclined planes and screws different?
a screw is a rotating inclined plane. like an inclined plane wraped around a cylinder.
Is there a screw that is also an inclined plane?
No, a screw is not an inclined plane. Although a screw can be used to convert rotational motion into linear motion, it is fundamentally different from an inclined plane, which is a flat surface that is slanted at an angle.
How is a propeller an inclined plane?
Propellers of a boat or an aeroplane are literally a continuous inclined planes on an axle. Screws could also be described as an inclined plane on an axle. The work being done, however, is quite different: propellers push or pull a fluid - air or water. As with simple inclined planes, the incline angle is proportional - the greater the slope, generally speaking, the greater the force required to move it through the fluid. Meaning that the propeller is shaped in the form of a Wing which produces lift when it moves through the air. They are not considered a flat plane. However, some wings can be a flat plate design and produce lift.
