Answer 1

Given that: Draw the free body diagram from equilibrium equation sigma M y = 0 -640 (0.6) - F_Cx (0.4) = 0 F_Cx = -640 times 0.6/0.4 F_Cx = -960 N sigma F_y = 0 F_cy + 330 = 0 F_cy = -330 N sigma = 0 -F_Bx (0.6) + F_Cx (0.6) - F_Cx (1.2) = 0 F_Bx = -330 (0.6) - (-960) (1.2)/0.6 F_Bx = 1590 N \r\n sigma m_x = 0 -0.6 F_By - 640 times 1.2 - F_Cy times 0.4 = 0 0.6 F_By = -768 - (-330) (0.4) F_By = -636/0.6 F_By = -1060 N F_By = -1060 N downarrow sigma F_y = 0 F_Ay + F_By + 640 = 0 F_Ay + F_By = -640 F_Ay - 1060 = -640 F_Ay = 420 N F_Ay = 420 N uparrow sigma F_x = 0 F_Cx + F_Ax + F_Bx = 0 F_Ax = -F_Bx - F_Cx F_Ax = -1590 - (-960) F_Ax = -630 N
