In a direct shear test, the shear strength parameters of a soil are commonly obtained by plotting shear stress at failure against:
Correct answer: D. Total normal stress on the shear plane
- A. Vertical settlement of the specimen
- B. Pore pressure at the ground surface
- C. Water content after drying
- D. Total normal stress on the shear plane
Explanation
The direct shear test provides failure pairs of shear stress and applied normal stress. Their strength envelope is used to estimate cohesion and the angle of shearing resistance.

About Soil Mechanics and Foundations
Soil mechanics examines index properties, phase relationships, classification, permeability, seepage, compaction, consolidation, shear strength and earth pressure. Foundations apply these principles to bearing capacity, settlement and shallow or deep foundation selection, with clear distinction between compaction, which expels air, and consolidation, which expels water over time.
