STEP
3
The machine is switched ON & the load is gradually increased until the specimen is fractured and the required load is noted down.
STEP 4
Calculate the double shear strength of mild steel plate.
| Width of the failure plane 'w' (mm) | Thickness of the failure plane 'd'(mm) | Area of cross-section (A=w*d) mm2 | Failure Load P (kg) | Double Shear Strength (P * 9.81)/2 A (N/mm2) |
|---|---|---|---|---|
STEP 5
Observation and Result
| Width of the failure plane 'w' (mm) | Thickness of the failure plane 'd'(mm) | Area of cross-section (A=w*d) mm2 | Failure Load P (kg) | Double Shear Strength (P * 9.81)/2 A (N/mm2) |
|---|---|---|---|---|
