In a singly reinforced beam

Steel possesses initial stresses when embedded in concrete
Plane sections transverse to the centre line of the beam before bending remain plane after bending
Elastic moduli for concrete and steel have different values within the limits of deformation of the beam
Compression is borne entirely by concrete

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