Civil Engineering MCQs
Q If p1 and p2 are mutually perpendicular principal stresses acting on a soil mass, the normal stress on any plane inclined at angle θ∘ to the principal plane carrying the principal stress p1, is:
  • A A. P1−p22+p1+p22sin2θ
  • B B. P1−p22+p1+p22cos2θ
  • C C. P1+p22+p1−p22cos2θ
  • D D. P1+p22+p1−p22sin2θ
