From that page: "...creep deformation does not occur suddenly upon the application of stress. Instead, strain accumulates as a result of long-term stress. Creep deformation is "time-dependent" deformation." This sounds exactly like what we are talking about... until you get to this: "Generally, the minimum temperature required for creep deformation to occur is 30% of the melting point for metals." By my calculations, that would be about 750 degrees F. That is one hot piano. Kurt -------------- next part -------------- An HTML attachment was scrubbed...
