Question

1. the worm gear in a vex iq motor is an example of what simple machine?

○ lever
○ screw
○ wedge
○ pulley

Explanation:

A worm gear consists of a screw - shaped worm that meshes with a gear. A screw is a simple machine that converts rotational motion into linear motion (or vice - versa in some cases) and uses the principle of an inclined plane wrapped around a cylinder. A lever is a rigid bar that rotates around a fulcrum, a pulley uses ropes and wheels to change the direction or magnitude of a force, and a wedge is a triangular - shaped object used to separate or hold things. Since a worm gear has a screw - like component (the worm), it is an example of a screw - type simple machine.

Answer:

Screw
