DESCRIPTION : A specified mean load (which may be zero) and an alternating load are applied to a specimen and the number of cycles required to produce failure recorded. Generally, the test is repeated with identical specimens and various fluctuating loads
RANGE OF EXPERIMENTS :
1. To Perform Fatigue Test
TECHNICAL DESCRIPTION :
This machine is used to test the fatigue strength of materials. This is a rotating beam type machine in which load is applied in reversed bending fashion. 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 completer cycle of reversed stresses in all fibers 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 are recorded by a Digital counter. An interlocking system puts off the motor at specimen failure. Machine meets requirements of IS 5075 – 1969

DESCRIPTION : The Rockwell scale is a hardness scale based on indentation hardness of a material. The Rockwell test determines the hardness by measuring the depth of penetration of an indenter under a large load compared to the penetration made by a preload.[1] There are different scales, denoted by a single letter, that use different loads or indenters. The result is a dimensionless number noted as HRA, HRB, HRC, etc., where the last letter is the respective Rockwell scale RANGE OF EXPERIMENTS : 1. To Measure the hardness of given specimen using Rockwell hardness tester. TECHNICAL DESCRIPTION : Test loads 60, 100 & 150 kgf for trsts on Rockwell A, B, C, scale. Automatic Zero setting dial gauge.
