My family has owned and operated a Crane Service for 30+ years and I am well versed in Crane signals, driving big trucks and trailers, rigging, etcalong with other quot;hands-onquot; type jobsWould this help me in the Marine Corps as an Engineer?
You dont get to choose your career reallyYou take a test and it tells you what you qualify for but if you are elegable for engineering then that will be extremely helpful for not only you but your fellow marines and the military!
Buoyancy - any object placed in a liquid, like water, must take up enough space in the liquid (displace enough liquid) to equal the mass of the object in order for it to floatThat's why naval vessels made of steel can float in the ocean - the 'weight' of water they move out of the way equals the weight of the shipBut if you throw an I-beam into the ocean, she's a goin' down to Davy Jones.
The ball floats because of air pockets created when one balls up the foil the flat sinks because there isn't any air pockets only it's mass and density.
Buoyancy and shapeThe balled foil has air trapped inside the ball providing the buoyancy to cause the 'ball' to floatThe flat foil doesn't have any method to trap air, so its sinksShape and buoyancy allow even steel ships to float in water by displacing their own weightHowever, if the water is still and the flat foil piece small enough, about a penny size, you might be able to 'float' the flat foil by gently placing it on the surface of the water, it will be held on top by the surface tension of the water molecules.
