...He has a swing speed of 152 mph and has to carry a persimmon, steel shafted drive in his bag incase he breaks both long drivers he has in the bag. I would assume he's SOL until he finds a shaft with enough torque to keep the shaft from breaking, but not too much torque where it effects his ball flight.
I guess I'm having trouble understanding this, though it may be OK. My questions:
(1) What do you mean by "enough torque"? It sounds like you mean a shaft with a "torque" rating higher than some number (like 3.5 degrees), but I'm not sure.
(2) If that's what you mean by "enough torque", why should that have anything to do with breaking shafts? My own reasoning would be:
- Maybe the shafts are breaking from torsion stress and maybe not. Bending stress? Shearing stress? I suspect both are at least as likely as torsional stress.
- Even if it is torsional stress, I'd expect that torsional STRENGTH, not torsional FLEXIBILITY, would be the key. Why would you expect torsional flexibility to prevent breakage?
