After loading an elastic body, its length in the x -axis direction increases by 0.0005 cm in cm, while its length in the y -axis direction decreases by 0.0001 cm in cm and the angle between these two directions decreases by 0.0006 rad. Show the normal strains ɛ, Ɛy and the shear strain yry. Find the principle normal strains with direction. Draw the Mohr circle.

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.
