Wheels are inherently a bunch of pivoting around a fulcrum

Wheels are inherently a bunch of levers pivoting around a fulcrum.

A lever is a bar with balance point called the fulcrum. In a wheel, the fulcrum is in the centre. The fulcrum is the point against which a lever is placed. The outside rim of the wheel is like a handle of a lever.

Wheels reduce frictions, they dig into the ground and rotate ( pivot ), turning around sturdy rods called axles. They provide leverage, a cart with bigger wheels is easier to push because bigger wheels work like bigger levers, multiplying the pulling or the pushing force.

Such melding of different peoples is a kind of Ethnogenesis. Ethnogenesis (from the Greek “ethnos”-people- and “genesis” -origin-) is a process by which a group of people is gathered to form a new ethnic group. These people may be ethnically associated with the new group or be outsiders who self-identify with the values/thoughts/ideas of the new group.

More specifically, this particular example is Passive Ethnogenesis, because people come together in a group that creates cultural-identity relationships, in this case being fans of the national football team.
