Q:If the car can turn the four wheels 90 degrees, then the roadside parking is not particularly convenient? Is it a technical problem or other problem that leads to a car wheel that can turn to 90 degrees?

Audi has been the concept car is done, the specific way is to become a spherical tire.

Q:Why quickly wink to see the wheels of rotation, you can see the moment the shape of the wheel, like a still picture?

It should be the frequency of your blink and the frequency of rotation of the wheel to form a relationship, which led you to see a series of pictures are wheels in the same position, so that your brain into a short 'static' wheel picture. There is an experiment that is the same: when the frequency of rotation of the wheel and the frequency of the human eye to receive the screen is the same, we see the wheel is likely to be still!

Q:What is the hard drive and pedal hard?

Vacuum is not enough! check! Vacuum assist pump

Q:i just wanted to know who invented the wheel

Based on diagrams on ancient clay tablets, the earliest known use of this essential invention was a potter’s wheel that was used at Ur in Mesopotamia (part of modern day Iraq} as early as 3500 BC. The first use of the wheel for transportation was probably on Mesopotamian chariots in 3200 BC. It is interesting to note that wheels may have had industrial or manufacturing applications before they were used on vehicles. A wheel with spokes first appeared on Egyptian chariots around 2000 BC, and wheels seem to have developed in Europe by 1400 BC without any influence from the Middle East. Because the idea of the wheel appears so simple, it’s easy to assume that the wheel would have simplyhappened" in every culture when it reached a particular level of sophistication. However, this is not the case. The great Inca, Aztec and Maya civilizations reached an extremely high level of development, yet they never used the wheel. In fact, there is no evidence that the use of the wheel existed among native people anywhere in the Western Hemisphere until well after contact with Europeans. Even in Europe, the wheel evolved little until the beginning of the nineteenth century. However, with the coming of the Industrial Revolution the wheel became the central component of technology, and came to be used in thousands of ways in countless different mechanisms.

Q:Do these tires fit my wheels?

The wheels you listed are factory F-150 wheels for your particular year model, and the 265 tires should fit fine. Looks like you should be good to go.

Q:I have a 2008 jeep wrangler, 4 door version. I‘ve noticed that when I‘m in 4 wheel drive, if I am going slowly and turning the wheel (usually in a parking lot, driveway, etc.), it feels like one wheel stops turning or something. The steering wheel actually starts to shake. It seems to work okay when I‘m driving straight. I can‘t tell with turns when driving faster but it seems to be okay. But there is a definite difference when driving like 1 to 7 miles per hour. Feels like it is having trouble going and the wheel shakes.I‘m a 4 wheel drive novice but our other vehicle (a large family type SUV) does not do this when in 4 wheel drive.Is this normal for a jeep? Any other issues I should check?

Are you using four-wheel-drive in the Jeep on roads / parking lots with good traction? Don't do that! Part time four-wheel-drive systems have a simple transfer case splitting the power between the front and rear. They should only be used when the road surface is slippery enough that the wheels will lose traction. Wheel slip is required to prevent exactly what you are feeling in your Jeep. Your family sized SUV probably has a full time, or All wheel drive system. In that drivetrain, a more sophisticated center differential replaces the transfer case, and allows all four wheels to spin at different speeds if required. Keep the Jeep in Two-High unless you really need the four-wheel-drive. You can damage the vehicle, otherwise.

Q:Please, help me translate this term - wheel over position to portuguese/spanish (but it is preferable to be in portuguese)Ex.: "the wheel over position ... is achieved when Thorn Island is ahead at 1.31 miles"

If I had to choose just one translation? I would choose the King James trans lation. But when I study I use both the King James and NIV. The King James is by far the best and most accurate. But there are a few verses while accurate could have a better translation of some words. That is where the NIV comes in. By reading and comparing them in study you can get a much better understanding of the full and true meaning of what is being told to us. Not that either is wrong, it is just a matter of degree of accuracy. The only way of doing better. Would be to be an expert in all of the languages in which the texts were written in and translated from. If you have choose just one translation let it be the King James. God bless

Q:What‘s different on a back bmx wheel to a front bmx wheel? Can I just swap my back wheel around with my front? If not, why not? Can I spray paint my hubs without affecting them technically? Thanks

Front wheels will not fit in back, and back wheels won't fit in front. Front wheels don't have sprockets and there is no way to attach one. Rear wheel axles are too thick to fit in a front fork. To spay paint a hub, you would have to remove all the spokes, and then rebuild the wheel afterwards unless you didn't care how bad it looked

Q:You know theres always the one you pick that has a shuudering, wobbling wheel. What is the explanation why this happens on a shopping cart? I ask because im about to purchase a used stroller with the same problem and would like to know why it happens so i can fix it. Danke!

Who says it cannot be used as an exhaust pipe? There are factors that make it a much more expensive alternative construction material for that purpose, but copper is well capable of channeling the exhaust gases away from an engine at those elevated temperatures. -Copper is a LOT more expensive than steel. To make an exhaust system out of copper pipe would raise the msrp by atleast a factor of 4 when compared to a steel system of similar design. -Copper is less durable than steel pipe, meaning the system would not last as long as a steel system of similar design. Frankly, I really cannot find any benefits to using copper rather than steel.

Q:There are 3 wheels in a F2K trebuchet: 2 wheels attached to the arm, and one guide wheel attached to the frame.Can they be any size? Do they all have to be uniform? Anyone know if there are ratios?

A chilly air inlet will no longer advance MPG. It will advance HP at complete throttle easiest. the upward thrust in capability is the consequences of burning extra gas, no longer an advance in efficiency, or decrease fee of preclude. in any respect diverse power settings there is another decrease it extremely is controlled by potential of potential of your outstanding foot.
