Archimedes Interview!

“Give me a lever long enough and a fulcrum on which to place it, and I shall move the world.”

Vocabulary: 

Fulcrum: The point on which a lever rests or is supported and on which it pivots.

Lever: A rigid bar used to help move a heavy load with one end when pressure is applied to the other.

Load: The weight on the other side of the lever. 

What we did in this experiment was we got a fulcrum, load, and a lever. And we had a sensor that measured in nodes. We had to use the ruler (lever) and the sensor which we pushed down hard on the other end of the ruler. We had a fulcrum underneath the lever located in the middle. We would move the fulcrum to out finger each trial. A real life example would be like when you put a rock underneath a spoon and the spoon has mashed potatoes, then you make the spoon balance by evening the weight out. Then you push on the spoon, that is an smaller scale of what we did. The spoon is the lever, the rock is the fulcrum, the mashed potatoes are the load and your hand pushing down on the spoon is the input force. 

Here is our data!
