A screw is essentially which simple machine wrapped around a cylinder?

A SCREW is essentially an INCLINED PLANE wrapped around a cylinder. ASVAB Mechanical Comprehension tests simple machines. The threads of a screw form a spiral inclined plane; turning the screw converts rotational motion into linear motion and provides mechanical advantage (a screw with closer threads requires more turns but less force). The six simple machines: lever, inclined plane, wheel and axle, pulley, wedge, and screw. A WEDGE is two inclined planes back-to-back. Recognizing the screw as a wrapped inclined plane is commonly tested.
