Problem 7. [Concepts: Allowable stresses and factor of safety] Two aluminum rods AB and AC support a vertical load P. The allowable tensile stress for the aluminum is Gallow = 150 MPa. a) If P = 20 kN, determine the required diameters of the rods AB and AC. b) If the diameters of the rods AB and AC are 10 mm and 8 mm, respectively, determine the largest vertical force P that can be supported.

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.
