6. Lever
There are two parts that make up
the lever. The bar, which is called
the arm and the fulcrum or pivot
point. The lever helps us lift things
easily.

"
The Incline Plane is made up of a straight plane
that is tilted up. Heavy objects can be moved
from lower levels to higher levels."

These screws help hold these objects together. Can you think what else screws
hold together?
14. Pulley
A Pulley is a made up from a wheel that is
wrapped with a cord or rope. A pulley
changes the direction of force and makes it
easy to hoist or lift objects.
