Which of the following types of stress is directly related to soil's ability to resist sliding along any plane inside it?
Compression Stress
Shear Stress
Bearing Stress
Capillary Stress
For downward seepage in soils, how does effective stress change with increasing depth?
Effective stress decreases due to additional pore water pressure.
Effective stress remains constant.
Effective stress increases linearly.
Effective stress decreases then stabilizes.
Which formula is used to compute the effective stress at any point in a soil layer?
What is the definition of primary consolidation in fine-grained soils?
The time-dependent settlement caused by soil fabric adjustment
The settlement caused by vertical load compression
The change in volume caused by water expulsion from soil pores
The saturation of soil voids due to capillarity
What factor determines whether a soil is overconsolidated or normally consolidated?
The soil's current pore water pressure
The vertical effective stress compared to past maximum stress
The shear strength under applied load
The horizontal stress distribution within the soil
In a soil sample undergoing secondary compression, which of the following is true?
It happens before primary consolidation ends.
It occurs after excess pore water pressure dissipates.
It is unaffected by soil fabric adjustment.
It leads to immediate settlement.
In the shear strength formula 𝜏 = 𝑐 + 𝜎 tan 𝜙 , what does 𝑐 represent?
Shear stress under peak load
The effective normal stress
The cohesion between soil particles
The frictional angle of soil
In a triaxial test, what does the deviator stress (Δσ) represent?
The difference between the maximum and minimum principal stresses
The total stress applied to the soil sample
The pore water pressure within the soil sample
The normal stress on a failure plane
What is the significance of the Over Consolidation Ratio (OCR) in soil analysis?
It predicts the vertical strain due to surface load.
It determines the shear strength of cohesive soils.
It assesses the past stress history relative to current stress.
It measures the pore water pressure within fine-grained soils.
The shear strength of soil depends on three primary components. Which of the following is NOT one of those components?

Cohesion and adhesion between particles
Interlocking and bridging of particles
Horizontal stress equilibrium
