The section of a retaining wall is shown Figure $02-663$A$.$ In this problem, $H_1=7\mathrm{.}1m,H_2=6\mathrm{.}5m,t_1=t_2=0\mathrm{.}6m,B=4m.$ Neglect the effect of the soil at the right side of the wall and consider $1$ meter length of wall. Determine the following:

$10.$ The resisting overturning moment $($righting moment$)$ in $kN$ m$.$

A$.956$

C$.1044$

gown in Figure ME$56-$GH$42$ is gs$.$ The soil is assumed to exert se of footing. For this problem, $m,b=2m,c=1m.$ Neglect
