The wheels, axle, and handles of a wheelbarrow weigh W = 55 N. The load chamber and its contents weigh WL = 623 N. The drawing shows these two forces in two different wheelbarrow designs.

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, choose the alternatives that are true. Note: the x-axis is horizontal and the y-axis is vertical and both have their origin at point D. Data: P = 332N 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. True or false?
