Summary[edit]
DescriptionMetalFatigue 005.jpg | Fatigue studies of short compression springs were made on a machine also developed at NBS. In this device the motor and adjustable eccentric from a Krouse plate bending machine were utilized, allowing eight springs to be stressed simultaneously at two levels. Stress levels are computed by measuring the change in pitch of the spring when in the no-load, minimum-load, and maximum-load positions. Electrical contacts stop the motor if any specimen fractures. | ||||
