    Default What is the strength of an average human's jaw?

    Like in PSI? What's the hardest thing we can break?

    According to this article the average biting force of the human jaw is 162 PSI.
    The trouble with fighting for human freedom is that one spends most of one's time defending scoundrels. For it is against scoundrels that oppressive laws are first aimed, and oppression must be stopped at the beginning if it is to be stopped at all.

    There's a big difference between bite strength in Newtons and psi, mind. One is force, the other is pressure (force per unit area). Hardness is another issue entirely: force and pressure, if they're measured directly, will be measured using something relatively soft so it doesn't damage the teeth. It doesn't matter if you can theoretically bite hard enough to crack a rock if your teeth will shatter first.

    Is there any particular reason you ask?

    Yeah I think they use several indices as to penetration etc.

    Once saw a documentary with a guy and a mako shark, testing ultrafine mail armour, so the shark could bite, but not penetrate the underlying surface, since the teeth would be stopped by the mail, the sharks bite is rendered reasonably annoying, nothing more.

    Sharks ofcourse bypass the rock/teeth problem by just growing new ones.

    Stupid, lucky sharks. I want new teeth.

    We can exert 4 tons of force in our bite. Or something like that
