Powerful Pivots and Shifting Shadufs

Last Monday, we studied powerful pivots, fulcrums, levers

and how to make a shaduf.

Here we are in the backyard discovering that if one moves the fulcrum, they can use the

use the board as a simple machine to move heavy objects.

Now, you may be asking yourself ...what's a shaduf?

It was a simple machine built by ancient Egyptians to move heavy loads such as buckets of water.

The farmers would use a shaduf to transport the water from the Nile River to a ditch or a water cistern.

As you can see the board, balanced on the fulcrum can handle heavier loads than our human arms ever could!! The idea is to pivot the board around - ummm maybe we can use ours to

transfer that pile of dirt into the back gardens?

Oh No! The Shaduf was shafted!!

I guess using rope to connect wood is not constructive but rather distructive.

Nails were a good invention!!!

Trial and error, try and try again.

It worked better with nails but I didn't take pictures of that for some reason ????

All in all, it was fun and a great way to learn!!
