TORSION TEST ON MILD STEEL
Objective
To study the mechanical properties of mild steel under torsion.
Apparatus used:
Torsion testing machine,Troptometer,Micrometer,Scale.
STEP
1
Measure the Initial Diameter of the torsion test sample at two or three places and the average value is obtained.
Torsion Test Sample
STEP
2
The gauge length of the beam is restricted at 180mm.
STEP
3
Now the specimen is chalked out on the gauge length for understanding the effect of torsion.
STEP 4
Insert the specimen into its position within the torsional experimental setup.
Drag the Specimen
STEP 5
Start the motor and slowly apply the twisting load on the specimen.
STEP 6
Graph.
