Two weights, A and C, are fixed to a bar, B. Their masses are: A = 60 kg, B = 230 kg,C = 45 kg. B is, in turn, connected to a fixed vertical post by a hinge and a support cableD.

Consider the force P applied at point A on the plate of the figure shown (image 1). Assuming that the weight of the plate is negligible, and that the horizontal force F, as well as the reactions Dy and Dx in the joint D balance the plate shown in the figure. Note: the x-axis is horizontal and the y-axis is vertical and both have their origin at point D. Data: P = 332N Which option is right? a) if the plate had a weight of 332N (applied vertically downwards in the center of the plate), the reaction Dy on the plate should be vertical downwards so that the plate still remained in balance in that position or b) if the plate had a weight of 332N (applied vertically downwards in the center of the plate), the reaction Dy on the plate should be vertical downwards so that the plate still remained in balance in that position
