The Trap-Jaw Ants

Trap-jaw ant

I found a very nice article in BBC News, Science/Nature section, about trap-jaw ants. The first paragraph said: “Trap-jaw ants bite with a force of over 300 times their own bodyweight…,” Grab your calculator, mate! If we assume a human averages 70 kg is designed by nature like ant, then the power of his jaw is:

Jaw clamping force = 300 x 70 kg = 21,000 kg.

If we assume an average city car fully loaded with fuel and passengers is about 1,500 kg, then the number of cars which can be lifted by a stroke of this jaw is:

Number of cars = 21,000 kg / 1,500 kg = 14 cars.

A really powerful lightweight structure created by nature :).

    I’ll say it again then..
    “Kun, how about making an article that compares your beast against some animals from the wild? I mean in terms of strength, capacity, yadda yadda yadda.. etc”…

    Arief: Thanks for the link, mate. I read all the article and it is much more detailed. I think all lightweight structural engineer must go back to nature. 🙂

    Goio: Well, automatically every comment from you by default will be classified as spam. Hehehehe. Kidding, mate! 😀 No I didn’t delete anything. No previous comment.
    Yea that’s a good idea. Now I need to think of the comparison. BTW, insects are great reference in term of design and structure. Their limbs are light and slender but strong. And most importantly, insects have gone through many millions years of evolution process and still keep the basic configuration of their anatomy. That means they are high-efficient and highly optimized creatures.
