This equipment is used for studying the effects of fatigue using a rotating cantilever specimen.
A spindle specimen is attached to one end of a rotating shaft held to the base by self aligned bearings. Load is applied on the spindle producing a sinusoidal bending stress. Digital revolution counter keeps account of the number of revolution when failure occurs. A limit switch is provided to stop the rotation when specimen fails.
- Influence of bending stress.
- Influence of different radii at fracture section.
