RCC Structures Design
If the depth of actual neutral axis of a doubly reinforced beam

All listed here
Is greater than the depth of critical neutral axis, the concrete attains its maximum stress earlier
Is less than the depth of critical neutral axis, the steel in the tensile zone attains its maximum stress earlier

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