    Ax, Ay, Bx should all be 20 kN. You can find at least two by equating the sum of forces to 0 and then checking using momenta, or vice versa.

    Your work is illegible to me. Try for example when you need to upload images with detail.

    This is my answer to the question. The answer about the forces acting on the points is on the left side, and the forces acting on the joints are on the right side (i,ii,iii,iv). I also checked if my answers would sum up to zero by adding the forces along the x and y-axis.
