A $5-ft$ square, $2-$ft deep spread footing is subjected to a concentric vertical load of $60$ k and

an overturning moment of $30ft-k.$ The overturning moment acts parallel to one of the sides

of the footing, and the top of the footing is flush with the ground surface and the groundwater

table is at a depth of $20$ ft below the ground surface. Determine whether the resultant force

acts within the middle third of the footing, compute the minimum and maximum bearing

pressures and show the distribution of bearing pressure in a sketch. Determine the size of

the equivalent uniformly loaded footing and compute the equivalent bearing pressure.
