WHAT’S HAPPENING

In the class 1 lever, a downward force on the

load side is counteracted by a downward

force on the effort side. In the other two

levers, the load force is downward and the

effort force is upward. In all three levers,

you should see that the closer the spring

scale hook is to the fulcrum, the more

effort force it takes to lift the load.

Convert the model into a class 2

lever by changing the location

of the fulcrum and joint pin.

Hook the load to the load arm. Repeat

the measurements with the spring

scale. This time, the load arm and the

effort arm are on the same side of the

fulcrum. What do you observe?

Hook the load to the load arm. Repeat the

measurements with the spring scale. Again,

the load arm and the effort arm are on the

same side of the fulcrum, but the effort force

(the spring scale) is closer to the fulcrum

than the load. What do you observe?

Convert the model

into a class 3 lever by

changing the location

of the joint pin.
