If you have one point on the wheel negatively charged, and move a positively charged magnet around it, it would move. \nOr, if you want something less manual, you can motorize one wheel w/ alternationg positive and negative charges around the edges, and then have another identical wheel on an axle right next to it, so as the first wheel turned, the second one would have to turn so that the opposite charges would line up.\nI'm not sure if the second one would work, but i tried. Good luck! =D

Alex is the largest bicycle wheel manufacturer in the world.  On their lower end wheels, such as the X2100, the quality control is much lower than on their higher-end wheels.  What this means is that you have a chance of it being a good wheel, or a bad wheel.  At 560g per rim, they are pretty heavy.\n\nAs far as "the straight scoop" - if the wheel works for you  - then use it!  Buying a good wheelset can be very expensive, and for the casual rider, it's possibly not worth the expense.\n\nIf you decide to move beyond economy class wheels, go to http://oddsandendos.com/ - Mike Garcia hand-builds some of the best wheels in the business, and his prices are very low (for high-qualtiy, hand-built wheels!).

A fixed wheel means that there is no freewheel associated with the cog. It's usually just a single cog threaded onto the rear hub, held in place by a lockring.\n\nFixed wheels can be found on track bikes, as well as many bike messenger's bikes. Look at it this way, if the bike is moving forward, the pedals will turn forward. If the bike is moving backwards, the pedals will turn backwards.\n\nIf you find yourself on a fixed gear bike and it's moving, remember this one thing: DON"T STOP PEDALING. You'll end up launching yourself over the handlebars.

if you're talking shaft out of balance you need an accelerometer\nother two look for steps in something, as in something is there or not there.\nThe accelerometer measures force

Consider the five basic machines, The lever and fulcrum, The inclined plain, The wheel and axle, The screw and the pulley.\n\nStart with a boyscout pine block racer kit, sand the wheels so that the tread is rounded rather than flat to reduce friction. for the undriven wheels put the nails in the wheels and deposit a liberal amount of petroleum based oil on the axle. This will cause the plastic to swell slightly for a good fit to the axles to prevent wobble, be sure to clean all the flash off of the nails first and polish them.\n\nThe driven wheels willneed a fixed axle that connects the wheels.

i use my board to get around because i can't do many tricks. i have two different types of wheels on my board. They are these funny Death Kenny Blind wheels on the left side and Element Oval Tree wheels on the right. A good website is the one down below. But find wheels that suit your personality.

so that they roll. why are wheels round?

The wheel, think of the things that would not be with out the wheel

They all actually would tilt the same way when going around a curve.  \n\nOn a two wheeler, the driver has the ability to lean into a curve to compensate for the tilt.  If they didn't, then they would end up being thrown off or tipping over.   Four wheelers cannot tilt into a curve (unless the pavement itself tilts, as at a racetrack).  They will tilt to the outside of a curve, and put more weigh on the outside wheels.\n\nIf the net force (down and outward) on the center of gravity does not go through the wheel of a two wheeler, it tips over.  If that force on a four wheeler goes outsdide the wheel base, it tips over.

This will probably not help, but the big tables used by a "Draftsman" tilt a lot and may suite your purpose. There may be a lot of old drafting tables around for sale at low cost, because much of the modern drafting (mechanical drawing) is done on computers these days. Search Yahoo for "drafting desks or tables" and see what they look like. Then go on Ebay and see if any are for sale inexpensively. One advantage might be that drafting tables are outfitted with big flexible arms that slide on the table surface to help the draftsman draw straight lines etc. That might help the disabled person somehow. They also may have good local lighting attached to them. But they're probably going to be big and heavy and take up a lot of floor space, so if you want something lightweight and portable you probably have to look elsewhere. Some tilting fixture exercise or medical rehabilitation machines might fit the bill.

the company with that name was bought out by GKN. Use to be called "Armstrong Rim & Wheel Mfg Co" but now owned by "Gkn Armstrong Wheel Inc." but this is more agriculture wheels.\n\nThe only other reference is another Armstrong company that was bought out by pirelli tires long ago.

Gyroscopics.\nThe wheels act as gyroscopes.  Precession causes any tipping to appear to the rider as a change in steering, which the rider finds easier to control using the handle bars.  Motorcycle riders use this effect by leaning over to one side to help change directions.\n\nWhether there is or isn't such a thing as "centrifugal" force depends on whether you are in a linear or a rotational frame of reference.

If it's just the scroll wheel on an optical mouse, you can try Start-->Control Panel-->Mouse and check the setting for the wheel. But because the wheel portion is a physical device (unlike the optical portion), it can fail.\n\nYou can try rapping and tapping the mouse on semi-hard surfaces to see if some vibration will help the wheel set back properly if so. Tap it on a hard desk covered by a few sheets of paper, for example.\n\nMake sure you try using the wheel in several different applications to ensure it's not just a problem with one application. If it's just a problem with one application (such as your web brower) there could be a setting found from a menu such as Tools-->Options that will allow you to set how you would like the wheel to operate.\n\nFinding a way to open it and clean and check inside would be best. You can also try compressed air through any gaps or edges in the housing of the mouse to try to blow loose the gunky dust that can accumulate in computer mice.

A bicycle is a wonderful example of an object that's unstable at rest, but stable in motion. My other favorite example is a broom balancing upside-down on the palm of your hand. Let's take a moment to look at the broom because it will help to understand the bicycle. \n\nWith the broom exactly centered above your motionless hand, nothing pushes it to one side and it balances. It's in equilibrium-it experiences no overall forces. In principle, it can stay that way indefinitely, but in practice it never does. The slightest shift of the broom's center of gravity to one side and over it goes. Any disturbance that shifts the broom away from equilibrium gives rise to forces that push the broom still farther from equilibrium, so the equilibrium is unstable. Any object that has no base of support-the polygon formed by its contact points with the ground-has an unstable equilibrium and tips over when disturbed. That instability stems from the fact that its center of gravity always descends when it's tipped and it releases gravitational potential energy as a result. Potential energy-energy stored in forces-is so intimately related to the forces themselves that whenever an object can release potential energy by heading in a certain direction, it naturally accelerates in that direction. \n\nSo the broom is unstable in your motionless hand. But if you move your hand, you can stabilize the broom. You do this by endlessly moving your hand under the broom's center of gravity. If the broom starts to tip to the left, you move its handle to the left to place that handle under the broom's shifted center of gravity. In that manner, you keep returning the broom to its equilibrium. Even though the equilibrium is naturally unstable, you keep helping it out and make it dynamically stable-stable in motion. \n\nNow let's shift to the bicycle. Like the broom, an upright but motionless bicycle is in an unstable equilibrium. If you're really skilled, you can balance it by shifting your weight around to keep the overall center of gravity above the wheels. However, there's a much easier way to balance the bicycle: drive forward! Once the bicycle is in forward motion, it steers automatically and places its wheels under the overall center of gravity. Unlike the broom example, where you have to think in order to push the handle under the center of gravity, the bicycle does this for you automatically. If the bicycle starts to fall over to the left, the front wheel steers left and the bicycle drives its wheels under the overall center of gravity. The bicycle returns to upright all by itself, even when you have no hands on the handlebars. \n\nThe automatic steering occurs for two reasons. First, there is gyroscopic precession that occurs when the spinning front wheel experiences torques from the ground. When the bicycle tips to the left, forces from the ground twist the spinning wheel so that its angular momentum shifts from leftward to rearward. This complicated precession effect causes the wheel to steer left toward the left. \n\nBut the more important source of automatic steering is that the tipped bicycle naturally flexes about its steering axis and turns its front wheel in the same direction as the tip. If you tip the bicycle left, the wheel pivots so as to steer the bicycle left. The fork and frame design are important to this effect. The tipped bicycle can reduce its gravitational potential energy by flexing and, as I mentioned above, this capacity to lower potential energy leads to forces that cause the tipped bicycle to flex. When you tip the bicycle to the left, it steers left and thus manages to reduce its gravitational potential energy-the bicycle's center of gravity descends slightly. Together with gyroscopic precession, this automatic steering makes the bicycle's wheels drive under the overall center of gravity so that the bicycle keeps returning to upright. So the forward-moving bicycle is like a broom w
