The Tesla500 Youtube Channel is at it again with an impressive build and experiment. David Kronstein the creator of the Chronos has attached a camera to a specially modified mower and blade assembly to shoot what a lawnmower does directly on the blade’s edge. The mower was only run at 1/2 speed, to avoid a camera failure, resulted in about 180 G-forces at the edge of the camera.
Needless to say, it really shows how good the camera is at withstanding abuse. While we do not condone you do this with any camera it is cool to know it can be done and still have beautiful high speed imagery to go with it. Congrats to David for the successful build! The G-forces involved would kill any living thing with a brain in seconds hence why a camera is a good subject, Please don’t try this at home! Watch the video below: → Continue Reading Full Post ←
A new study released by Georgia Tech led by Alexis Noel, Mechanical Engineering Ph.D. student at that institution has revealed the hidden nature and mechanics of how frogs use their squishy and sticky tongues to eat their prey. With acceleration forces reaching 12 Gs these prey experiment over 4x that of astronauts in a rocket leaving the atmosphere at 3 Gs.
With the use of high speed video cameras at over 1,000fps the study was able to reveal the complex motion, eye retraction and viscous properties of the frog’s elastic tongue while catching prey. The frog uses a mucus like substance on the tongue to generate the stickiness necessary to envelop the insect prey without ejecting them off from the brutal speed and force generated. → Continue Reading Full Post ←
