Certain animals have their body parts arranged around a central point. A starfish is a good example of this, which is known as radial symmetry.
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.
