Water & Block Archimedes Physics
Not Enough Votes
Lets talk about Water & Block Physics for SE2.
After watching SE2 teasers about water leaks (Please excuse the pun) I love the direction it is going in to create new challenges for engineering. However, there is one thing I noticed, all the armor blocks in those leaks float. So a little clarification is requested and a suggestion if I may, remembering that this is only a game. Would a metal duck still float?
The Questions:
- If we assume (Light & Heavy) armor blocks are solid pieces of metal, how come they defy the Archimedes principle and float in the examples?
- Are the armor blocks in these examples only for conceptual iteration of water?
- Or are the new armor blocks somehow hollow or lighter than water?
- How is water displacement/ buoyancy being calculated?
The Suggestion:
- Armor blocks should SINK- One of the best things about SE is obviously the problem solving. "Anvils don't float", the expectation with water would be to build boats that actually float because of the Archimedes principle. But if armor blocks act more like Styrofoam instead, it removes the challenge. Additionally, if attempting to create a submarine, armor blocks always floating would hinder achieving neutral or negative buoyancy and ballast.
Again, I love the direction it is going. I would like to see some realism in relation to mass and displacement for water in relation to blocks. This is why all armor blocks should sink, unless they are hollow like an Oxygen or Hydrogen tank or have some other specifically designed purpose.
I like this feedback
In SE1 Light & Heavy Armor are not solid pieces of metal (ex. small grid light armor block: Volume = (0,5 m)³ = 0,125 m³; Mass = 20 kg; Density = 20 kg / 0,125 m³ = 160 kg/m³; density of steel = 7850...7870 kg/m³).
The same is probably true in SE2.

It depends, would a metal boat float?

To expand on what xyz xyz said, for light armor:
density of steel: density of steel 7,750 to 8,050 kg/m³
big grid
side = 2.5m
volume = 15.625 m³
mass = 500 kg
density = 32 kg/m³
mass of equivalent solid block 121,093.75 to 125,781.25 kg -> the big grid light armor block is < 0.42% solid
small grid
side = 0.5m
volume = 0.125m³
mass = 20 kg
density = 160 kg/m³
mass of equivalent solid block 968.75 to 1,006.25 kg -> the small grid light armor block is < 16.52% solid
As for heavy armor:
big grid
side = 2.5m
volume = 15.625 m³
mass = 3,300 kg
density = 211.2 kg/m³
mass of equivalent solid block 121,093.75 to 125,781.25 kg -> the big grid heavy armor block is < 2.73% solid
small grid
side = 0.5m
volume = 0.125m³
mass = 112 kg
density = 896 kg/m³
mass of equivalent solid block 968.75 to 1,006.25 kg -> the small grid heavy armor block is < 92.5% solid
So, in regards to question N°3, it isn't that the new blocks are hollow, they've always been hollow.
In all cases the density of the armor blocks is lower than the density of water, so they should float as per Archimedes principle.

Do we want armor to float?
