My science project "The Pulley Station"



Hey guys the photo above is my science project.
how it works: as you pull the rope and put an object on the hook it will lift the weight up!


Notice: everything is made of wood. ** Even the pulley !!


I made it like this (out of wood) because back in the old days there were only wood pulleys because iron didn't come out.

    Alisha,you have done a very good job with your pulley station which is strong enough to lift heavy load. You put into use some of the concepts we learned about in Mecahnical Systems. Good job!
