"Bite force" - "Measured in psi"

"force" - "psi"

#34 - penelo (10/31/2015) [-]
'psi' is for measuring pressure and pressure measures force per area.
What is your point?
User avatar
#45 - Nhatkiem (10/31/2015) [-]
My point is. Pressure is not a force. It is force per unit area. Its the same reason why we don't mistake mass and force. Or volume and area.

My point is, the chart should say bite pressure, and not bite force?

I understood your point, but I think you are being needlessly harsh with a graph that clearly means to inform the masses and therefore uses often incorrect language to attract attention or to simply be easier to understand.

Don't agree I was being harsh... just saying the verbiage was wrong.

This clearly isn't about being wrong or right. It's about appealing and making it easier to understand, when you say 'bite pressure' it definetly doesn't ring as good as saying 'bite force'. We aer trying to appeal to the commonfolk, and this includes the people that know jack about maths and physics (some people like arts and literature and chose such things as careers).
And pressure can indeed be considered a measure of force: to a given area (a square inch) you got yourself a given force.

#49 - Nhatkiem (10/31/2015) [-]
But then you wouldn't call it pressure anymore would you?

Just cause people choose different career paths doesn't make the verbiage any more or less important. I mean, we have words and definition for a reason no? Use the right words for the right meanings. Pretty simple. I'm not going to write a whole dissertation on this haha. Guess we'll just have to agree to disagree... sorta?

The thing is (and you learn this when you're in high-school in those philosofy classes that no ones gives half a fuck about), there is a barrier between scienific language and ordinary language. The first cannot be ambiguous, each term has its meaning and mistakes are not tolerated, it is used when you communicate with people that share the same work/career/etc. The last one however, is when you ty to get the point across to someone that doesn't have those concepts in their mind (or if it does, doesn't use them with the same agility as you for a bunch of reasons), if you talk to that person with specific terms, they will probably discard the information you're offering either because they cannot understand or because their brain doesn't classify it as important. Not everyone that you meet will know the same things you do (you probably won't know everything everyone tells you) and so you will have to adjust yourself to the situation.
All this because of a unit of measurement that I don't even use (bar and Pa are just fine by me).

The number decreases as the tooth size increases.
A 2" diameter tooth (hippo) is about half the psi as the same crushing force from a croc with 1" diameter teeth.
Now, a croc doesn't have 1" diameter teeth, they are sharp. If the croc had infinitely sharp teeth, the psi would be infinite.
Think of it like a magnifying glass, the sun's rays will warm you but if the same amount is concentrated on a small area and the energy density increases? Poof goes the ant.

TL;DR - PSI is pressure density, not overall force.

I do not think that the sharpness of the teeth is what comes into play when mentioning this.
#42 - autoxx (10/31/2015) [-]
You're welcome to your opinion but please tell me how 100psi, spread over a 1sq" tooth surface is not the same as 1000psi spread over a 0.1sq" tooth?
As the surface area decreases, the pressure per surface area increases.

#43 - penelo (10/31/2015) [-]
That's all fine and dandy, but you gotta consider that an animal has more than one tooth, the force that the jaw applies is distributed by several of them. The measuring device used probably has a pre-determined area, like 1 square inch.
They aren't going to measure the force done by the tip of a single tooth, that would be ludacrous. You have to be a bit more practical in your way of thinking.
#52 - autoxx (11/01/2015) [-]
That's why it's an ambiguous unit of measure.
People recognize the unit because it is so prevalent but it doesn't apply well to what is measured.

No way am I going to say the same twice, this should even be common sense

Someone like that sounds like they're in an excellent position to emotionally manipulate people. There's more than just physical abuse.

I'm not sure how you'd be abused by that kind of person, but I'd imagine in that scenario you pretend they're a rugby ball.
