Answer

\sum M_B = 0:\; 9\,A_X - 5.5\,F_E = 0

Answer

\sum M_B = 0:\; 9\,A_X - 3.5\,F_E + B_X = 0

Answer

\sum M_B = 0:\; 9\,A_X - 3.5\,F_E = 0

Answer

\sum M_B = 0:\; 5.5\,A_X - 3.5\,F_E = 0

Answer

\sum M_B = 0:\; -9\,A_X - 3.5\,F_E = 0

Answer

\sum M_B = 0:\; -9\,A_X - 3.5\,F_E + 9\,B_X = 0
