A lever does this by increasing the distance through which the force acts. In this experiment, you will show that the closer the fulcrum — or the pivot point of the lever — is moved toward the ...

A lever is a simple mechanism that uses a bar to pivot around a fixed point called a fulcrum. Levers can be joined together to form linkages. Simple linkages can be used to change the direction of ...

A trebuchet functions similarly, except that the pivot point of the lever is placed off-center (in this case, farther away from the load) to amplify the force that launches the projectile.

Class 1 levers usually have a beam that is rigid, long and thin, like a ruler. Between the two ends of the beam is the fulcrum, or pivot point, which is the point at which the beam can balance and ...
