In summary: A: At A, the rod makes an angle theta with the horizontal (7/24), causing the weight (40 N) to be applied at an angle alpha (3/4) to the horizontal, so that the rod and the bar are in equilibrium.C: The bar and rod are in equilibrium, but if the rod makes an angle theta with the horizontal, where tan theta = 7/24, the bar will be displaced (by x cm) to the right or left.AC: If the rod makes an angle theta with the horizontal, where tan theta = 7/24
