Abstract

In an experimental study of the behavior of an iron rod fixed at one end and subjected to torsion at the other it was found that there is a marked tendency of the rod to remain in the state of strain which it has acquired. When the torque was raised to a relatively high value and then reduced to zero the strain tended to remain. It was found to disappear in about twenty-four hours however. The residual strain in the rod is evidently the result of the reluctance of the metal to change its molecular arrangement.
