An Introduction
A look at 6 simple machines to help make
work easier not harder.
• Wheel and Axle
• Lever
• Inclined Plane
• Pulley
• Screw
• Wedge
Let’s Begin!
Wheel and Axle
The wheel and axle work together to help
things move from one place to another
more easily!
Wheel and Axle
Wheel and Axle Bicycle
A bicycle is an example of a simple machine
that uses a wheel and axle to help make
