The building slab is subjected to four parallel column Part A loadings. The resultant force acts through point (12 m, \( 10 \mathrm{~m}) \). Suppose that \( F_{3}=12 \mathrm{kN} \) and Determine the magnitude of \( \mathbf{F}_{1} \). \( F_{4}=9 \mathrm{kN} \) Express your answer to three significant figures and include the appropriate units. Figure 1 of 1 Part B Determine the magnitude of \( \mathbf{F}_{2} \). Express your answer to three significant figures and include the appropriate units.
