Cranes and Pulleys

Hello again guys! Here are all of my crane and pulley Projects;

/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\

My first Project was " The Groovy Crane Arm." (They sure do say "Groovy" a lot. Do they?)

Me using the crane arm.

What I'm doing in the picture above is turning the chopstick to gather up the hemp cord which pulls up the small bucket. Cool huh?

/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\

My next project was "Turning Crane."

Really cool part of the turning crane.     

                                                                                      
There is another part of the crane, but I forgot to take a picture.( Silly me! :-P )
It was a cup with a magnet attached to some hemp cord. What I did was I put the hemp cord over the tube above and pulled the cord, that lifted up the cup. It's kind of like those cranes at scrap yards. You can also turn the tube to move the cup.

My next project was "Compound Pulley."
                                    

The compound pulley is my favorite
experiment. It's so cool!

When the cord gets pulled, the bobbins (aka: The pulleys. ) lift the cup up like a pulley.

/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\

And my Last Project was " Fetch a Pail of Grooviness."

I really like this project. It resembles getting
water from a well.

                   















This project is kind of like the groovy crane arm, except it involves the groovy box. When you turn the crank, it brings up the pail. But if I turn it the other way, it brings it down.
