Two footings, one circular and the other square, are founded on the surface of a purely cohesionless soil. The diameter of the circular footing is the same as the side length of the square footing. The ratio between their ultimate bearing capacities (circular : square) will be:

When a column is located near the property line and an isolated footing cannot extend beyond the boundary, which footing is provided to connect it with an inner column?

Two columns carrying unequal loads2. Heavy stanchion/steel column load3. Bridges/heavy loads at depth4. Load bearing wall
