Question

1. what simple machines make up the compound machine below? how do they help someone do work?

Explanation:

The compound machine (corkscrew) consists of a screw, a lever, and gears (or wheel - axle in the gear - like parts). The screw converts rotational force into linear force to pierce the cork. Levers (the two arms and the handle - lever) amplify force, reducing the effort needed to pull the cork. Gears (or wheel - axle) can also help in force amplification and changing the direction of force transmission, making it easier to rotate the screw and lift the cork.

Answer:

The compound machine (corkscrew) is made up of a screw, levers, and gears (or wheel - axle - like gear parts). The screw converts rotational motion to linear motion to pierce the cork. Levers amplify force to reduce the effort for pulling the cork. Gears (or wheel - axle) help in force amplification and direction change for easier rotation and lifting of the cork.
