Which of the following equation represent hydrostatic pressure in its purest form?
(a) σ1+σ2+σ3=0
(b) σ1+σ2+σ3=constant
(c) σ1=σ2=σ3
(d) σmax+ σmin
The question was posed to me during an online interview.
I would like to ask this question from The Mohr in division Failure Envelopes & Earth Pressure of Geotechnical Engineering II
