Science riddle 8?

Question

Sorry dudes, I've been having Yahoo! Answers angst.... I will try to get on everyday and check up on my question.

The Movement

What movement made by which muscle or limb or libmbs is, without using any object such as a lever, the most powerful the human body is capable of?

Anyway, props to Erwin Brecher.

Answer to the sunken sub (which I do belive was the last one I put up):

Water preassure pushes perpendicular to a subarine's hull at every point, at the bottm as well as at the top and sides. When a sub settles on a clay or sandy bottom, the water layer may be squeezed out from beneath the hull, robbing the sub or mushc of its upward buoyant force. In effect, the downward forces can then ''glue'' the sub to the bottom.

Good luck and have fun!

I would rather not dwell on past questions, if you have a problem with a past problem, e-mail me.

Answer 2

The gluteal muscles are the three muscles that make up the human buttocks. The gluteal muscles are formed of the gluteus maximus, gluteus minimus and gluteus medius. The gluteus maximus is the uppermost of the three muscles, and is commonly known as the butt cheek. It is the largest of the gluteal muscles and, by some definitions, is the most powerful muscle of the human body. Its action is to extend and outwardly rotate hip, and extend the trunk.

Answer 3

No I don't think so cause there is air in the inside of the sub.
