9. A hook is subjected to three forces A, B, and Cas shown. Force A = 35 kN and force B = 45 kN. a) If the resultant of the forces is 80 kN and is acting along the positive x-axis, determine the angle a. b) If a = 60 degrees, what is the value of force C such that the resultant of forces A, B, and C acts along the x-axis? c) For the forces A, B, and C to be in equilibrium, what is the magnitude of the resulting force C?

Bars

In civil engineering, bars refer to steel reinforcement bars or rebars. These are structural members primarily used for reinforcement purposes in masonry works. A bar is characterized by its cross-sectional area, which is negligible compared to its length. Bars are usually manufactured by steel which is uniform throughout the length, or by meshing multiple steel wires. Other materials of the bar include carbon steel, glass fiber, carbon fiber, and basalt fiber. The reinforcing bars are coated with epoxy resins and other materials to enhance some of their properties including corrosion resistance.
