EXPERIMENT 3 SHEAR TEST
1. AIM
To determine the shear strength, which is the maximum shear stress that the material can withstand before failure occurs.
2. APPARATUS
Technical data
Specimen diameter = 6mm
Specimen length = 55mm
Specimen Material = Electrical Grade Copper
3. PROCEDURE
3.1 Measure the specimen diameter
3.2 Place the shear anvil and lower shear support with specimen inserted between the compression plates and remove all slack between the components.
3.3 Slowly pump the handle of the test unit hand pump.
3.4 Record the force and elongation on the digital gauge.
3.5 Continue to apply force in increments of 1KN and watch the applied force rise.
3.6 Apply the force until the specimen shears.
3.7 Remove the specimen.

5. CALCULATIONS
5.1 Calculate and compare the shear strength of the specimen.
5.2 Drawn a graph of Force and shear deflection.
6. CONCLUSION
Expert Answer
The shear strength of the copper specimen is 89.5 kN. This is slightly lower than the shear strengt...
