To replace force$-$couple systems with an equivalent force by specifying the magnitude and direction of the equivalent force and the location where the force needs to be abolied. Figure$3$ of $3$ Part D $-$ Analyzing a system of forces acting on a concrete slab. The concrete slab shown in the picture is subject to four forces, $F_1=195lb,F_2=345lb,F_3=565lb,$ and $F_4=225lb.($Figure $3)$The dimensions are $d_1=9\mathrm{.}0ft,d_2=21ft,d_3=4\mathrm{.}0ft,d_4=16ft,$ and $d_5=9\mathrm{.}5ft.$Determine the equivalent resultant force by specifying its magnitude and its location $(x,y)$ on the slab.

Express your answers, separated by commas, to three significant figures. $($s$)F_R,x,y=lb,ft,ft$
