If the length of a combined footing for two columns l metres 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 is the distance of centre of gravity of column loads______________?
A. y = L – (l – ) )
B. y = L/2 + (l –
C. y = L/2 – (l + )
D. y = L/2 – (l – )
