If I'd known then what I knew now, I would have gone to a maritime college/academy and taken that route. I would love to be an officer on a cargo ship or cruise line. There's a maritime college in New York that's like $18,000, but you can turn around and pay that off within a few years. I wish I'd done that instead of go into the military. ha ha!

This is probably due to the incorrect way that someone decided to label metric scales in kg and the improper conversion that everyone does of kglb. This is a case where the imperial system is correct, as pounds are a unit of force and slugs are the imperial unit for mass.

I know the difference in density between freshwater and saltwater is minimal but just wondering since cruise liners tend to be designed for saltwater, would they float on freshwater. That might sound like a ridiculous question, but in engineering the calculations are extremely precise, or perhaps the bottom of the hull might sink a bit lower in relation to the water line. Anyone know? Edit: nevermind I finished watching the video and my question was answered. Brilliant video.

@KonradTheWizzard

Essentially yes. Slight correction though: more or less dense than water. How heavy it is does not matter, it is the relation between weight and volume. Something can be as heavy as a ton and float if it has a volume greater than 1m³, it can be light as 1 gram and sink if it displaces less than 1cm³. It has to be less dense than 1kg per liter (or 1 ton per cubic meter). Neat - right?

Жыл бұрын
Archimede's Principle states that a body immersed in a fluid experiences an upthrust *equal* to the weight of the fluid displaced. The average density of the total volume of the ship and everything inside of it (including the air) must be less or equal than the same volume of water. That's what keeps it floating. When an anchor is dropped into the water it sinks because the anchor on its own has more density in the volume of water that surrounds it. The upward force that the water produces against the anchor is not strong enough so it keeps sinking until it hits rock bottom. For example: imagine you are weak and skinny and a bigger more muscular guy pushes you, you would fall over (the bully wins). now imagine that you are much bigger and muscular than the same guy and he push you again, he will not be able to. Same principal. In easy terms, the anchor is more stronger than the force of water so it goes right through it.

Okay maybe I'm just an idiot but I swear the calculation of the brick is wrong. The volume comes out at 0.001m cubed which is a millimeter. A brick with those dimensions does not have a millimeter cubed of volume? If we work with the centimetre measurements, we have 20x10x5=1000. 1000cm is 10m. So we have 10m cubed not 0.001m cubed. So why when calculating in two different units of measurement do you ultimately get two different number of metres cubed after any necessary conversions? Someone please explain this to me I'm baffled and no one else has said this so I'm wondering if I'm just missing something incredibly obvious. 😅
