The free-body diagram in the drawing shows the forces that act on a thin rod. The three forces are drawn to scale and lie in the plane of the screen. Are these forces sufficient to keep the rod in equilibrium, or are additional forces necessary

ignore diagram. It didn't come out well. Please use the link below to get diagram

I say , more forces need because for a body to be in equilibrium, forces acting on it must be equal and opposit in direction

Take the top force, break it into two components, one horizontal, and one vertical. Now read your reasoning in your answer in light of that.
