Q51
Effective stress is
A.
the stress at particles contact
B.
a physical parameter that can be measured
C.
important because it is a function of engineering properties of soil
D.
all of the above
AnswerAnswer: Option D
Solution
Answer: Option D
Solution:
Effective stress: It is the stress transmitted through soil particles at their points of contact. This is critical in understanding the behavior of soils under load.
A physical parameter that can be measured: Effective stress is a measurable quantity calculated as the total stress minus pore water pressure.
Importance: Effective stress is a key parameter because it governs the engineering properties of soil, such as shear strength, compressibility, and permeability.
Since all the statements are correct, Option D: all of the above is the correct answer.
