10 As shown, a pipe is anchored to a wall at point A. (Figure 2) During the pipe'sinstallation, several forces are applied to the pipe at different locations. If F = 17.2 lb ,F2 = 18.4 lb, F = 14.8 lb, F = 11.1 lb , dj = 0.350 ft , d2 = 0.650 ft , and dz =0.500 ft , what is MR, , the net moment about point A due to these forces? Assumethat moments acting counterclockwise about point A are positive whereas momentsacting clockwise are negative.Express your answer numerically in pound-feet to three significant figures.• View Available Hint(s)Πν ΑΣΦvecMRAlb ftF2FF3dz
