F1 Chief mechanic

A team of mechanics is assigned to each car and another team to the preparation of the spare car. Their roles are split between engine, chassis, gearbox, and hydraulics on each car, and they don’t interchange responsibilities. Each is a specialist in his own area. There is also a tyre man whose is responsible for washing and stacking the tyres for each driver and each practice, qualifying, or race. Selected mechanics also double up as the pit crew during pit stops. Overseeing and co-ordinating all these people is the chief mechanic.
