Indeed. Nature is the perhaps the most ingenious invention! Biological life tends to assimilate better than any tools than man has created, no matter how advance, weaponized, or integrated they are.
Tell me more about these "3rd class levers"? I assume you must have VAST knowledge of mechanical applications and systems, and perhaps even electrical as well! HAHA!
As for weapons, perhaps you can help me with a dilemma! Look at my gallery and see the guns that I have? Could you help me understand the mechanism more well? Here's the link to the image:[link]
I can see how gas from the fired bullet pushes "some" lever back to eject the fired cartridge, in which the lever springs back into place to reload a new bullet and firing it. But how the more intricate items work nearby the housing unit and trigger is still a puzzle to me. I mean, does the trigger just keep the mechanism "rolling" automatically while "pulled back?" Thanks.
