(Solved): Calculate the resultant moment of forces \( \mathrm{F} 1=70 \mathrm{lb}, \mathrm{F} 2=90 \ ...
Calculate the resultant moment of forces \( \mathrm{F} 1=70 \mathrm{lb}, \mathrm{F} 2=90 \mathrm{lb} \), and \( \mathrm{F} 3=26 \mathrm{lb} \) about point A. Express your answer in \( \mathrm{lb} \). ft and use a negative sign if the resultant moment is in the CW direction.
