Vet någon om antal G-krafter för en GP-förare?

Jag fick denna fråga i ett mail från en medlem, men kan inte svaret. (Killen som frågade har fått en länk till denna tråd så vi hoppas att någon klok människa kan svaret. :)


"Jag undrar hur många g-krafter en gp förare kommer upp i under acceleration och retardation?"

Ungefär. i F1 kan man komma upp i maximalt 5G (enligt vad jag snabbt kunde surfa fram) men de har _mycket_ bättre förutsättningar mtp 4 hjul och låg tyngdpunkt. Kanske att man kan få till 2G på hoj genom en sänka (kompression).

5. Brakes are the most powerful control. Comparing the distances from the center to the top of the graph with the distance to the bottom of the graph reveals that maximum braking G-forces are about 50 percent stronger than maximum acceleration G-forces.

6. But what is more amazing is that maximum cornering G-forces are about 30 percent bigger than maximum braking G-forces. The former ones correspond to the distance from the center of the graph to the left and right edges. The latter one corresponds to the distance from the center of the graph to the bottom edge.

A look at the data shows middle-of-the-road acceleration numbers exiting Turn 6 at 0.66g, though coming out of the final, slower corner it struggled, with a best of 0.63g, putting it third from the back. Though despite the “soft” feeling brakes, it still produced some of the best braking g-force numbers going into Turn 14 at -1.21g.

But where the Yamaha shined was its class-leading maximum grip figure in Turn 2, sticking to the pavement at the tune of 1.2g as a result of the balanced set-up and solid chassis. Though it didn’t produce the highest grip in the final set of corners, the 1.3g it was capable of in Turn 15 put it at the pointy end of the field. It may not have been the easiest to get settled into a turn, but once on its side the chassis was a thing a beauty.
