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 k is the distance of center of gravity of column loads)
A] $$y = L - (l - x)$$
B] $$y = \frac{L}{2} + (l - x)$$
C] $$y = \frac{L}{2} - (l + x)$$
D] $$y = \frac{L}{2} - (l - x)$$
