A reinforced cement concrete footing as shown in Fig. 10.9 carries a concentrated load at P so as to produce maximum 

 

bending stresses due to eccentricities about x-x axis and y-y axis as 100

kN/m² and 150 kN/m² respectively. If the direct stress due to loading is 175 kN/m² (compressive), then the intensity

of resultant stress at corner B will be
