Inclined planes make moving from one level to another easier. Wedges seperate objects into smaller pieces when desired. Screws help fasten food and metal. Pulleys make moving a heavy object easier to lift up and down. Wheels and axles help rotate to allow "anything" to happen. (open doors, help objects move around, etc.) Levers make lifting objects easier to move.
What is the purpose of an inclined plane? Wedge? Screw? Pulley? Wheel and axle? Lever?
