Question

The property that cannot be determined from uni-axial compressive strength test of a rock sample fitted with strain gauges is

• A. Cohesion
• B. Poisson’s ratio
• C. Modulus of elasticity
• D. Dilation

Hint:

Cohesion requires shear testing; uni-axial test measures elastic moduli.

Answer 1

The Correct Option is A

Uni-axial compressive strength test with strain gauges measures elastic properties like Poisson’s ratio, modulus, and dilation but does not directly measure cohesion.
