What does the Uniaxial Compressive Strength (UCS) test measure in rock mechanics?
A. Tensile strength of rock
B. Compressive strength of rock
C. Shear strength of rock
D. Elastic modulus of rock
Answer: Option B
Solution (By Examveda Team)
UCS test measures the maximum axial compressive stress that a rock sample can withstand before failure.This is a fundamental strength parameter in rock mechanics.This Question Belongs to Geological Engineering >> Rock Mechanics And Rock Engineering
