Introduction

In an unknown time and an uncharted place, the ASPIRE crew has accepted the challenge to assist in the completion of a city being constructed of massive stones. They must work without the advantage of modern technology. They have agreed to rely primarily on the use of the six simple machines to accomplish their mission.

Before getting to work, two crew members, Harry and Pic, have used available materials to fashion themselves a teeter-totter just to give them something to do for fun.

This never seems fair. Drag the slider bars to move Harry and Pic until they have becomed balanced.
Harry weighs more than Pic, so you have helped Pic get an advantage in the situation, a Mechanical Advantage.

Simple machines give us an advantage by changing the amount, speed, or direction of forces. We are dependant on simple machines in many aspects of our lives.

From day to day do you find yourself using any of the six simple machines:
