Why do any cars go above 90mph? ever? when is it ever safe and necessary to drive in excess of this speed? Why is there no government control over the torque or horsepower in vehicles? Wouldn't it be easier to catch criminals and racers if only cops could drive over 90mph? Why aren't peoples licenses permanently revoked after 1 or 2 DUIs? Why are we obligated to keep giving DUI offenders 3rd and 4th and 5th chances just so their lives arent adversely affected?

The same response to these questions could be applied to gun ownership. Because one, those situations where people suffer because of this kind of behavior are the exception and not the rule, and two the government has decided that it is not justification enough to infringe on peoples rights to own a fast and powerful vehicle anymore than it is to prevent people from going hunting or shooting for hobby.

If peoples guns must be removed for the good of us all, despite there being reasons to want to own one ABOVE and beyond recreation, then why not stuff like fast cars and dangerous hobbies?

To be clear: my point is a nanny state can't and should not stop short of any one persons bias on what is good or bad. Either the state should do everything in its power to safeguard people against themselves OR we have to accept that the government will allow things that may be unsafe/harmful for people in certain situations. If you accept that 2nd part then give thought to the fact that just because guns are pointless to u, it does not mean they are pointless to everyone.

What are you talking about, both the penis' behind the wheels of these vehicles are probably American. Someone just fucking hates America(n).
Outmatched vehicles:
553 ft.-lbs. of torque at 2000 rpm and 310 HP (18:1 comp ratio w/dual-turbo chargers) with the Toureg

520 lb-ft @ 1,800 RPM- 6.6 liter w/300 hp @ 3100 rpm with bouncy there-

While both seem matched, the VW's the real piece of work.
Engineering be damned, the Germans pretty much extended their penises farther than any country with their fucking master -race shit.
Got to hand it to the insect-like attention to details, though....after WW2, a shitload of their engineers came to the U.S.

So, buy a Mercedes Benz and enjoy it....great car, until you need repairs...Ka-Chiniig!!

Pointless to sift it, but my first vehicle when I was 15 that I learned to drive on and went up steep faces I thought I would roll over and go down the hill. Was fun times in that vehicle, you dont appreciate those times until its NOW.

Vroooom.. I think it had 68 horse power, 70ft/pounds of torque and it was a 1.1 litre engine. But holy shit could it go places.

The hand rail is either not moving or it doesn't have enough torque and when people grip it, it stops moving

Tork, torque, torc. I actually don't like the sound of it now.

Yeah, call me a nerd but i was actually wanting to hear a hypothesis...

But now i think about it it's probably a 'how long is a length of string' argument. The tower has to be as long as it's cumulative weight based on gravity at different lengths from sea level. It's weight depends on the materials used and the structures at different points (base, flexible joints, etc)

Every different design for a space elevator probably has a different length and weight?

However i would be interested in how the forces / torque shape up on such a structure.
e.g. G at both ends, stresses at mid point pulling in both directions, flex, wind shear, torque, harmonics. Is it better at the equator than anywhere else?

BTW, for those of you that want to have MORE fun with the math aspect of all of this (if you want to try to figure out for example what equation you'll be using here...) go here: Wikiversity's link for Rigid Body States O' Fun! <---WARNING: LOTS of MATH!

Angular momentum, torque, and a strange geometrical shape with different areas of "spin" make for great WTF moments. I like torque the most though, it always provides the most fun through its various breakdowns in Physics...

I can defiantly see a college professor turning that little video into an impromptu test, "Watch this video: Now, assume that this thing has these dimensions and has this mass, also here are the independent velocities for the different areas (if it's a hard class will add in extra stuff like resistance, etc...)... Go ahead and tell me x, y, and, z...? You have twenty-five minutes.".

I really do like this video though. If I was a High School physics teacher my kids would understand what is happening here before they left my class. Screw honors programs and AP crap. All students deserve a chance to be great at something not just the ones that scored good on their tests in elementary (which in UTAH, this IS THE TRUTH!). Off-topic a bit, but I couldn't help it.

Must be selectively spinning the wheels midflight to generate torque to control attitude.

That is a beast of a machine, but I wonder how much more trouble it makes for itself because of the torque. It seems like it could climb half those slopes with only a fraction of the power if it weren't constantly losing traction.

Well, the electric motor is actually ideal for lots of torque, but I would imagine the battery life on that sucks all. Id prolly mod a gas engine generator on there to supply power.

This type of gear is commonly used so that you can have a gear ratio (mechanical advantage) that is a variable as a function of angle of rotation of the gear. Its difficult to tell just from this video if that is happening in this case (as oppose to simply having a z-constrained contact point, not unlike a helical gear). If the contact point moves from left to right in the x direction (perpendicular to the axles, in the direction from gear center to gear center) the leverage changes and so you can have a regularly variable gear ratio, which is useful for certain applications such as periodic motion generators.
One thing I am sure many of you didn't notice is that the gear on the far right is not touching the center drive gear at all, despite it only being slightly more distant from the drive gear. Indeed it is spinning in the opposite direction while still not interfering with the drive gear. It would take an extremely small axial motion for the drive gear to transfer its torque to the right gear and away from the left, and would likely result in extremely minimal galling and gear damage since the gear is pretty much kept in proper shape. In a standard spur gear, this would require the use of huge numbers of extremely tiny teeth, which anyone who knows their solid mechanics would tell you that they are very weak compared to something like this.


I came back just to upvote your comment, I almost forgot

Tried to find some more info on it: looks like it was an idea for a new differential for a vehicle that would help with traction in the same way a (torque sensitive) limited slip differential works. I couldn't find any info on if it is superior to other differential designs or even if it is used, except that the two gear model has very low gear efficiency (a good thing in this case).>> ^spaceman:
Very cool. But is there any benefit of these gears?


I couldnt find dick all about it either. I have a fetish for gears.

He used Dick, Fetish and Gears in the same quote, does that mean it grinds his gears?
