A steel tape having a cross-sectional area of 0.055 cm^2and a modulus of elasticity of 2.1x 10^6 kg/sq. cm, weighs 0.035kg/m. Its length is 30 m when standardized at a pull of 5.5 kg and supported throughout its length. Determine the tension at which the effect of sag will be eliminated by the elongation of the tape due to increased tension. * O 19.57 kgs. O 19.67 kgs. O 19.37 kgs. O 19.47 kgs. O 19.27 kgs.

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.
