This machine is light, compact & simple in design used to test the
fatigue strength of materials & to draw SoN diagram, used for research
institutes, laboratories, material manufacturers & various industries.
Machine is table model, no need of civil foundation.
Rotating beam type machine in which load is applied in reversed
Standard 8 mm diameter specimen is held in
special holders at its ends & 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.
The bending moment
is applied with a lever system and can be easily changed by moving a weight over the lever.
Maximum bending moment of
200 kgcm is applied & adjustable from 25 to 200 kgcm.
Total number of revolutions at which the specimen fails is recorded by
a digital counter.
The total number of digits of digital counter is eight.
after specimen fails.
Accuracy of applied bending moment + 1 %.
Optional - Machine with maximum bending moment upto
400 kgcm can also be offered.
Machine meets requirements of IS: 5075-1969.
