RCC Structures Design
If T and R are the tread and rise of a stair which carries a load w per square metre on slope, the corresponding load per square metre of the horizontal area, is

w (R/T)
w √(R² + T²)/T
w √(R + T)/T
w (R + T)/T

RCC Structures Design
If the length of a combined footing for two columns l meters apart is L and the projection on the left side of the exterior column is x, then the projection y on the right side of the exterior column, in order to have a uniformly distributed load, is (where x̅ is the distance of centre of gravity of column loads).

y = L - (l - x̅)
y = L/2 - (l - x̅)
y = L/2 + (l - x̅)
y = L/2 - (l + x̅)
