How many mechanics required to change a wheel formula one?

Answer 1

3 for each wheel ... two for the wheels (new and old) and one for the air gun.

The mechanic with the air gun is flanked by the two responsible for the wheels. As the mechanic with the air gun removes the wheel nut, the mechanic on his right grabs hold of the wheel. When the nut is off, the mechanic on the right removes the wheel and the mechanic on the left puts on the new wheel. The air gun mechanic replaces the wheel nut and raises his hand in the air to signify successful completion. The whole process should take 2 to 3 seconds.
