What would be the strongest possible material that has a density under 10,000 g/cm^3?
How is this different from the other thread that you started a few days ago?What would be the strongest possible material that has a density under 10,000 g/cm^3?
I was asking about an actuator, and now i am asking about a materialHow is this different from the other thread that you started a few days ago?
Yes but diamond is not the upper limit to the strength of a material sevral other materials have been discovered which are harder like https://futurism.com/mit-unveils-new-material-thats-strongest-and-lightest-on-earthDiamond has a density of a mere 3.5g/cm3, yet can withstand compressions up to 60GPa.
Well that's the sticky bit isn't it?... how an infinitely advanced civilization would create this (only limited by the laws of physics)
1. "Strongest", as in the best combination of Melting Point, Hardness, Yield Strength, Tensile Strength, Toughness, and Stiffness.
I'd say he is asking us to make some assumptions about that for the sake of story.That's even vaguer. Who is to say what "best" is?
That's actually showcasing strength-per-unit-density. i.e. density - and thus total mass - of the material is a constraining factor.Yes but diamond is not the upper limit to the strength of a material sevral other materials have been discovered which are harder like https://futurism.com/mit-unveils-new-material-thats-strongest-and-lightest-on-earth
The OP must ask himself what every sci-fi writer must: how much detail do I need to put in?
Does it need to be scientifically accurate, or does it just need to be plausible?
A good point.... if it's within the realms of our possible, then how "infinitely advanced" can this culture really be?
...the laws of physics... as understood by 21st century Earth, who only invented heavier-than air flight 12 decades ago.only limited by the laws of physics.
only limited by the laws of physics.
Which would include fabrication, alloys, heat treating, etc.I mean the current laws of physics.
