RCC Structures Design
If l₁ and l₂ are the lengths of long and short spans of a two way slab simply supported on four edges and carrying a load w per unit area, the ratio of the loads split into w₁ and w₂ acting on strips parallel to l₂ and l₁ is

w₁/w₂ = (l₂/l₁)³
w₁/w₂ = (l₂/l₁)²
w₁/w₂ = l₂/l₁
w₁/w₂ = (l₂/l₁)⁴

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
