Determine the magnitude and sense of the moments of forces F1, F2 and F3 about point A in Figure.
Consider Lx = 1.2m; Ly = 0.7 m; F1 = 12 KN; F2 = 6 KN; F3 = 15 kN
F1
Ly
F3
M1 = 14.4 kNm; M2 = -4.2 kNm; M3 = 0
Missed option - incorrect
-14.4 kNm; M2 = +4.2 kNm; M3 = 0
Selected Answer - Incorrect
M1-10 kNm; M2 = +3 kNm; M3 = 2 kNm
M1=-14.4 kNm; M2 = +4.2 kNm; M3 = 3 kNm
