← HistoryWhich outcome arises when compressive forces exceed stone's limits?
A)Crack propagation occurs through cleavage✓
B)Increased elasticity resists deformation
C)Plastic deformation initiates in aggregate
D)Shear resistance increases material strength
💡 Explanation
Tensile stress initiates crack propagation because intermolecular bonds break locally under pressure, therefore crack propagation occurs rather than flow which requires dislocations, and shear requires stress on a plane.
