Application and operation
This machine is used to test the fatigue strength of materials and to draw S-N diagram by research institutes, laboratories, material manufactures and various industries. This is a rotating beam type machine in which load is applied in reversed bending fashion. The standard 8mm dia. specimen is held in special holders at its end loaded such that it experiences a uniform bending moment. The specimen is rotated at 00rpm. By a motor. A complete cycle of reversed stresses in all fibres of the specimen is produced during each revolution. The bending moment is applied with a lever system and can be easily changed by moving a weight over the lever. Total number of revolutions at which  the
specimen fails is recorded by a digital counter. An interlocking system puts off the motor at specimen failure. Machine meets requirement of IS:5075-1969.
