If is the net upward pressure on a square footing of side for a square column of side , the maximum bending moment is given by
A)B.M = pb (c - a)/4
B)B.M = pb (b -a)²/4
C)B.M = pb (b -a)²/8
D)B.M = pb (b +a)/8

The maximum bending moment for a square footing under a square column, considering uniform pressure distribution, is given by the formula $B.M = \frac{pb(b - a)^2}{8}$, where $p$ is the pressure, $b$ is the side of the footing, and $a$ is the side of the column. This formula accounts for the difference in dimensions between the footing and the column, and the division by 8 is due to the distribution of forces and the calculation of moments for a square shape.
