A quick "back of the fag packet calculation" gives me the following:

Centripetal Acceleration = (v*v)/r = (214 * 214)/6.4 = 7155 M/S^2
i.e 70g constant acceleration.
Err , maybe need to get your cigarette packet checked
Is 7155m/s^2 ~= 70g ? (More like: 700g)
i can understand that valves might have an issue at 700g, but why would a chip care about being at 700g ?
