Why it is easier to lift a bucket full of water under the surface of water?
Because all that you are actually lifting is the bucket. The water is moving in it's own medium and so is weightless.
Where do you place the fulcrum to get the most lifting power from a simple lever?
A lever's mechanical advantage is the ratio of the effort arm to the load arm. The shorter the load arm, the greater the lifting power, so the closer the fulcrum is to the object being lifted, the better.

Why do you have pulleys on the wells?
Pulleys exist on wells to make it easier to remove the bucket. Once the bucket has gone down to the water, it is heavy and hard to lift straight up. So the pulley allows the person to pull down and/or at an angle to make the lifting easier. A block and tackle (a network of pulleys) could be used here to make the lifting even easier.
What type of lever system is described the deltoid abducts the arm?

Which part of the wheel and axle is the fulcrum?
The Fulcrum is not aboutthe wheel and axle.. it is the center of cravity of any vehichle. The usual example for this example is used when talking about a Forklift or maybe a Crane,when lifting heavy objects are lifted. It's about lifting any object than may cause the object lifted making the object lifting to callapse or falter.
