RCC Structures Design
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:

[(p₁ + p₂)/2] + [(p₁ - p₂)/2] sin 2θ
[(p₁ - p₂)/2] + [(p₁ + p₂)/2] cos 2θ
[(p₁ - p₂)/2] + [(p₁ + p₂)/2] sin 2θ
[(p₁ + p₂)/2] + [(p₁ - p₂)/2] cos 2θ
