Carefully, very carefully. If your wheel has good overall tension but is still out of true you slack the spokes on the protruding side with maybe 1/4 turn and then tighten the spoke on the disappearing side with equal amounts.
But I'd suggest you go visit www.sheldonbrown.com first, he's got a nice and helpful piece on his site about wheel trueing.
Get a spoke key of the right size and turn it in the right direction. Do note that it's an easy way to mess up a wheel. Uneven tension will make the wheel untrue, and too high tension can ruin both rim, spoke nipples and occasionally even the hub.
The only friction a spoke sees in use is air drag, which can be reduced by using oval spokes, and fewer of them. When building/trueing a wheel there's some friction in the threads, which is reduced by using a suitable spoke prep compound.
Friction is what happens when two surfaces are brought in contact with each other with a certain force.
Apart from choosing the materials, their surface contour and the contact pressure there really isn't anything you can do to "get" friction, it's a built in characteristic of the materials.
you cant tighten spokes on an ATV, they have solid aluminum or steel rims. but you can tighten spokes on a dirt bike by getting a spoke wrench and tightening the nipple at the end of the spoke closest to the rim.
There are many types of spokes. Some are the spokes on a bicycle, another are the spokes on a wheelchair, or you can even find them on baby carriages.
Spokes are examples of pre-stressed construction elements.
Spokes are found as part of wheels, for instance on a bicycle. They connect the hub to the rim.
a bicycle wheel?
No, but the spokes on a bicycle do.
360 / 30 = 12 , so 12 spokes in that wheel.
Bicycle spokes are usually made of stainless steel, although cheap/old bikes might have spokes of galvanized steel instead. Some high-end bikes have thick spokes out of aluminum alloy. There are occasional uses of carbon fibre spokes too.
Most spokes are metal, and metals are conductors.

Bike wheels are made out of three parts: 1 The center hub, the nave , 2 the rim, 3 the spokes. The spokes have hook's on one end, that are latched through the holes of the nave . The other end of the spokes are threaded and are put through holes in the rim and then fastened with a nut with a flattened head. This was the easy part. The difficult part is to tighten all the spokes equally so that the nave and the rim are in perfect alignment.
Really too complicated to answer here, better visit www.bicycletutor.com, www.parktool.com or www.sheldonbrown.com. But basically you loosen the spokes on the side you want to move the rim from, and tighten the spokes on the side you want the rim closer to. In reality there's a lot more to it, you have to watch out for roundness, spoke tension and wheel dish.
