The concrete slab shown in the picture is subject to four forces. \( F_{1}=140 \mathrm{lb}, F_{2}=195 \mathrm{lb}, F_{3}=580 \mathrm{lb} \), and \( F_{4}=220 \mathrm{lb} \). 3 of 3 (Eigure 3) Thendimensions are \( d_{1}=7.0 \mathrm{ft}, d_{2}=19 \mathrm{ft}, d_{3}=3.5 \mathrm{ft} \), \( d_{1}=16 \mathrm{ft} \), and \( d_{s}=10.0 \mathrm{ft} \). 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.
