So Isaac Newton had only 1/700th the bite force of a normal human? Pathetic.

Probably due to all the mercury and shit he was playing with as an alchemist

Every time I picture an alligator biting me I'm like I bet I could wiggle out or like somehow overcome it, because their jaws look so long and flat - like how much strength could they have? Certainly not more than a lion.

Well.

The closing force is significantly higher than its opening force IIRC. If you can close its mouth without getting bitten it's screwed.

Salt water Crocs are not tiny. Some alligators are on the smallish side comparatively, but there are big gators out there too.

Crocodiles are also one of those rare animals that don't "age" in the traditional sense. Once they reach adulthood, they continue to get larger and larger until they eventually starve or their organs collapse under their own body weight. They don't lose muscle mass or bone density or any of the usual issues we attribute to getting older.

Imagine having the build of a 25 year old at 100 and being 7+ft tall. That's how crocodiles age.

Yeah I've never seen one in real life, so I feel like like I'm not grokking the sense of scale.

Kind of like seeing a horse or moose for the first time (guess my hemisphere lol).

Here's a rough size comparison

[–] grrgyle@slrpnk.net 1 points 1 week ago

Yeah I'm still not getting it. Maybe I'll see one for real one day and then it'll click

Just remember these guys can grip an animal the size of a horse with their jaws, overpower it, drag it to the water and rip it apart.

I bet this is peak force is measured at the base of the jaw, meaning the teeth at the tip would exert significantly lower force. So it might be possible to escape a small alligator, I'm not sure.

There are lots of videos about croc bite force. With scales attached to their jaws and stuff. Shouldnt be hard to find.

This younger one was measured at the base with 820 pounds https://www.youtube.com/watch?v=cG7ruzhqB9Y&t=158

I can eat way more than 700 fig Newtons. This is bullshit.

[–] OutlierBlue@lemmy.ca 9 points 1 week ago (1 children)

Yeah but do you have the bite force to bite through all 700 at once?

[–] Kolanaki@yiffit.net 6 points 1 week ago* (last edited 1 week ago)

I would think... They're pretty soft.

Perhaps not after my jaw dislocates to fit them all in my mouth, though.

Given:

Bite Force of T. rex: 45,000 Newtons

Jaw Closing Distance: Approximately 0.3 meters

Energy=Force×Distance=45,000N×0.3m=13,500Joules

Say we have a typical 10w led lightbulb, how much could it power it for?

Time= Power/Energy=13,500J / 10W=1,350 seconds, or approximately 22 and a half minutes with a single T-Rex chomp, assuming 100% conversion efficiency

[–] qjkxbmwvz@startrek.website 7 points 1 week ago

Fun fact, the (rough) conversion efficiency of calories to mechanical joules in the human body (separate from the mechanical to electrical you're referring to) is about 25%


but this is about the same factor as going from calories to joules! So, for a human to put out 13.5 kJ of energy would require about 13.5 food calories (kilocalories).

Our ancestors had more bite force. It wasn't needed anymore.

Bite Force and Occlusal Stress Production in Hominin Evolution

[–] dylanmorgan@slrpnk.net 4 points 1 week ago (1 children)

How is this calculated? Presumably you could directly measure all but the T-Rex and pliosaur, but how are those bits forces calculated?

[–] MajorMajormajormajor@lemmy.ca 7 points 1 week ago

I'm no BiteForceologist but I was assume they compare muscle size, muscle attachment points, and mechanical advantage of extant creatures and then apply that data to fossils. So not 100% accurate, but not just guessing randomly.

[–] huquad@lemmy.ml 4 points 1 week ago

Bite pressure would be a more interesting comparison IMO. Of course a Trex is gonna have a massive bite force because it's dominated by size.

[–] AAA@feddit.org 3 points 1 week ago (1 children)

Forgot the bite force of Russian trolls and Chinese paid actors on any topic remotely concerning Ukraine or Chinese politics, and how the west is actually the bad guys.

Unlimited bite force.

Look around here lady, this is Lemmy.

[–] electric_nan@lemmy.ml 3 points 1 week ago

Did they run out of old tons or something?

so to bite harder i need crocs and seasalt, ok ok ok.
