Notes:

a. Hot-rolled flat heat treated at 1800°F/1 hr, A.C. + 1325 °F/8 hr, F.C 20 °F/8 hr to 1150°F , held for total aging time of 18 hr. Dynamic testing involved frequencies of from 813 to 571 cps in bending and from 3110 to 2097 cps in torsion.

b. Computed from (E-2G)/2G, where E is Young's Modulus and G is torsional modulus.
