If the Length of a Combined Footing for Two Columns

Multiple Choice

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 - )
