Which type of stress is usually most responsible for tensile cracking in rocks?
A. Horizontal stress
B. Compressive stress
C. Shear stress
D. Tensile stress
Answer: Option D
Solution (By Examveda Team)
Tensile stress causes rocks to crack when the stress exceeds their low tensile strength.Rocks are much weaker in tension than in compression.This Question Belongs to Geological Engineering >> Rock Mechanics And Rock Engineering
