A 3 m by 3 m square footing is sitting 1.6 m below the ground surface. The anticipated column loads include a moment (M=50 kN.m), a horizontal force (Qh=40kN, acting in the same direction as the moment) at the ground surface and a vertical force (Qv=260kN). Determine the minimum and maximum stress beneath the footing and draw the stress profile diagram to scale.
