What a great SteadiCam--oh, wait...

Eukelek says...

The entire arm seems to twist and fails at the joint of the arm on the camera which seems offset from the center of gravity of the weight and camera. Probably the cutting and snapping of a 1/4th steel bolt or something. Camera-weight need to be completely leveled flush (+/- 0.6°) by the awesome weights as a closed object system. I believe correcting this torsion by putting that universal joint center in line with the center of gravity of the camera-weight would prevent that torsion. This would mean that the joint center would have to be somewhere central in that column tube thingy. The over extension and over snapping can only be fixed with built-in stops, I dunno.

He went full extension...you never go full extension! I suspect the designers never intended for the camera to ever be beyond arms length. At full extension with that large a camera the pressure on all the components was too great.

Like Archimedes said "Give me a place to stand and a long enough lever ... oops!"

Man Flies Like a Bird Flapping His Own Wings

You're all fake!


hehe

also check this out someone already did a flapping one man flier ..probably on sift

"Built from carbon fiber, foam, and balsa wood, the Snowbird weighs just 94 lbs. and has a wingspan of 105 feet, which is comparable to that of a Boeing 737–amazingly, the Snowbird weighs less than all of the pillows on board.

The wings’ thrust is due primarily to a low-pressure region around the leading edge, which integrates to provide a force known as “leading-edge suction”. The wings also passively twist in response to the flapping. This is due to a structure that is torsionally compliant in just the right amount to allow efficient thrusting (”aeroelastic tailoring”). It should be noted, though, that twisting is required only to prevent flow separation on sections along the wing. It does not produce thrust in the same way as required by sharp-edged wings with little leading-edge suction."

Towing Fail

BoneRemake says...

The box is not even an issue, I dont understand what that message even meant.

the only thing a person should be baffled about on this video is how the frame rails bent like spaghetti.

go take a look at a truck cab and the space between that and the box, you can unbolt the box and drive the truck around just fine. there is a good inch gap on most trucks, there has to be for bending and torsion etc..

DAMN I WISH THRE WAS SOME BACK STORY !

A very small trebuchet that tosses tiny pies at bugs

Trebuchets, Ballistas, Mangonels and Onagers are all catapults..

However, a trebuchet works by using the energy of a raised counterweight to throw the projectile. i.e. they're powered by gravity.

Tho, since the device in this ad gets its power from those springs on either side..

Its design is closer to a torsion catapult like a Mangonel or Onager.

Generically referred to as just "a catapult".

[cause the only real difference is: Onagers use a sling. Mangonels use a spoon or basket.]

Sorry for nerdin' out.. I used to be reeeally into that sorta stuff. = P

Stomp the Yard II: Raize the Roof

She was the chief's daughter consigned to her privileges. He was a peasant boy from the other side of the river. Together, they would join forces to triumphantly overcome testicular torsion in a battle of epic proportions......

>> ^silvercord:
Please don't try this at home as it could lead to testicular torsion , a true urologic emergency and must be differentiated from other complaints of testicular pain because a delay in diagnosis and management can lead to loss of the testicle. Though testicular torsion can occur at any age, including the prenatal and perinatal periods, it most commonly occurs in adolescents, and testicular torsion is the most frequent cause of testicle loss in that population.



Testicular torsion affects males only.


This reminds me, time to feel my balls.

Samurai pulls off fastest submission in history -whole story

>> ^fissionchips:
Human limbs are incredibly weak in torsion. That's why attaching lever arms to your extremities (read:skis) is such a monumentally bad idea.

Which is why skis come with bindings that release under torsion. Though that doesn't stop stupid people from setting them too tight and destroying their limbs.

Good thing it was only my left knee...
