The rigid bar AB, attached to two vertical rods as shown in the figure, is horizontal before the load P is applied. If the value of P is 60 KN, the elongation in the Aluminum Bar is Steel Aluminum L- 3 m A= 500 mm L- 4 m A= 300 mm E= 200 GPa E = 70 GPa B C. 3.5 m 2.5 m

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 lengt…
