DIRECT SHEAR TEST ON MILD STEEL ROD
Objective
To determine experimentally , the ultimate shear strength in double shear of mild steel rod.
Apparatus used:
Universal testing machine, Shear attachments,Vernier calipers.
STEP
1
Take the mild steel rod specimen and determine the diameter of the specimen using vernier calipers.
STEP
2
The mild steel rod is placed in the shear attachments and placed into the Universal Testing machine.
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 on mild steel rod.
| Diameter(mm) | Area of cross-section (A=πd2/4) mm2 |
Failure Load P (kg) | Double Shear Strength (P * 9.81)/2 A (N/mm2) |
|---|---|---|---|
STEP 5
Observation and Result
| Diameter(mm) | Area of cross-section (A=πd2/4) mm2 |
Failure Load P (kg) | Double Shear Strength (P * 9.81)/2 A (N/mm2) |
