In the figure, using the conventional cartesian coordinate system in 2-D (right direction is positive x, left direction is negative x and upward direction is positive y, downward direction is negative y, CW negative, CCW positive), it is found that the reaction forces at point A are Ax = -400 N and Ay = -96 N. In this case, what are the internal forces at point C: normal force (Nc), bending moment (Mc), and shear force(Vc);   (Nc, Mc, Vc)?
