Because they are curved or they are slanted
The fan blades.
An inclined plane on a fan would be found on the blades. The curved shape of the blades creates an inclined surface that helps push air downwards or upwards, depending on the orientation of the fan.
You would find an inclined plane on the blades of an electric fan. The angle of the blades creates an inclined surface that helps move air efficiently.
The inclined plane on a fan is typically found on the blades. The angled shape of the blades creates an inclined plane that helps to move air more efficiently as the fan rotates.
An inclined plane could be found in the fan blade design, as the shape helps to push air efficiently. The wheel and axle are present in the motor of the electric fan, where the shaft of the motor rotates the fan blades to create air circulation.

If you consider one blade and extrapolate it, it becomes an archemides screw (an inclined plane wrapped around a core.)
An inclined plane is a surface with a slope. A ramp is an example, as are chutes, hoppers, and funnels. Since cutting blades have sloped surfaces, they are also inclined planes, and so knives, drills, chisels, and plows are examples. The twist of a screw is an inclined plane, including the Archimedes screw used for pumping water, as is the blade of the rotor of a windmill. All of these were in use in the Middle Ages. There are types of inclined planes, such as the airfoil, that were not in use then.
no they are leaning which is why they are called inclined planes
If you consider one blade and extrapolate it, it becomes an archemides screw (an inclined plane wrapped around a core.)
fan blades are inclined to an angle of less than 90 degrees. When a fan motor turns the blades, the blades move through the air at an incline; the inclined surface passing through the air pushes the air forward, as the air is scooped up by the leading edge of the fan blade and set in motion as it passes over the surface.
INCLINED PLANES: WINDSHIELDS, DOOR STEPS, GENERAL ZIPPERS WEDGE: PUSH PINS, NAILS, KNIVES, YOUR OWN TEETH, SLEDGE HAMMER, BLADES OF SKATE, RAZOR BLADE HOPE THIS HELPED YOUR HOMEWORK! *Some other examples of inclined planes are a sink, bathtub bottom, chair. Another common example of a wedge is an axe or staple.
