Is a pulley or screw or wheel and axle or lever a inclined plane?

Answer 1

To identify a simple machine, determine how it develops its mechanical advantage.

If the MA comes from the load traveling along the length of an inclined surface to reach a higher height, then the machine is an inclined plane. If the central axis of a helical shape is made to rotate, and because of that rotation a force applied by the helix causes a nut to move along the axial length, or causes the helix to advance through the nut, then the helix is a screw.

So if an ant crawls along the thread of the anchor bolt of a streetlight the ant is using that "screw" as an inclined plane. If a giant grabbed the helical ramp of a parking garage, and turned it until it had forced its way into the ground, the giant would be using the garage's parking "ramp" as a screw.

The type of machine is identified by how it is used and how it develops its mechanical advantage, not simply by its size or vernacular name.

Answer 2

None of those devices are inclined planes. An inclined plane is a flat surface that is tilted, like a ramp. The pulley, screw, wheel and axle, and lever are simple machines that provide mechanical advantage in different ways.

Answer 3

It is an example of an lever. Not an inclined plane.

Answer 4

A hammer is a lever......
