- thechao 3y agoWell below the G forces experienced by smart artillery. Solid state is pretty solid.
- MichaelZuo 3y agoNot for sustained minutes, a few miliseconds.
- zardo 3y agoThat's probably worse as the jerk must also be very high
- K0balt 3y agoAbsolutely. 20kg pushing evenly on a flat piece of glass an inch in diameter is no big deal. People are forgetting that small things are really, really tough. People have a bias against high forces because they’re made of meat.
- FredPret 3y agoI'm not going to do the calculation right now, but I wonder what G-force would be needed to deform a steel shell, for example. How much worse would it be if sustained over a long period?
- K0balt 3y agoIt’s 20kg of force evenly distributed on a little chunk of glass. It would be fine.
- K0balt 3y agoNope. 1 gram spacecraft, 20kg of thrust. Glass is tough. A 1 gram flat chip of glass with about 6cm2 of area (the proposed “spaceship” design) would withstand even more than steel by nearly a factor of two. People are freaking out about 20,000g, but you could push a flat disk of glass like that at about 60,000,000g before it failed. Good Glass has a compressive strength of about 1000 megapascals.
