For the square footing shown below, $B=10ft,q_{\text{m}\text{a}\text{x}}=5ksf$ and $q_{\text{m}\text{i}\text{n}}=1ksf.$

a$.$ Determine the value of the resultant force, $R$

b$.$ Determine the values of the applied load, P$,$ and moment, M

c$.$ Calculate the eccentricity of the resultant, $e,$ relative to the center of the footing

$q=(\frac{P}{A})[1+-\frac{6e}{B}]$
