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
Answer: Option D
Solution (By Examveda Team)
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.
This Question Belongs to Civil Engineering >> Soil Mechanics And Foundation
A should be correct, its indirectly computed using total stress (sigma) and pore water pressure (u)
It is not directly measured and not a physical parameter
The answer should be option (A)
It's not a physical property. It cannot be measured in laboratory therefore option B is incorrect
It should be D
Why not D?
