Fatigue Testing Machine Lab

This machine is light, compact and simple design used to test the
fatigue strength of materials and draw S-N diagram used for research
institutes, laboratories, material manufacturer and various industries.
Table model, no need of foundation.
This is a rotating beam type machine in which load is applied in
reversed bending fashion.
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 are recorded by a
Digital counter.
The standard 8 mm dia specimen is held in special holders at its ends
and loaded such that it experiences a uniform bending moment.
The specimen is rotated at 4200 rpm by a motor. A complete cycle of
reversed stresses in all fibres of the specimen is produced during each
revolution.
An interlocking system puts off the motor at specimen failure.
