Draw Stress vs strain curves, what are over reinforced section and under reinforced section

Question

Accepted Answer

Explanation of stress vs strain curves and over/under reinforced sections.

Stress vs strain curves show the relationship between the amount of force applied to a material and the resulting deformation.
Over reinforced sections have too much steel reinforcement, causing the concrete to fail before the steel does.
Under reinforced sections have too little steel reinforcement, causing the steel to fail before the concrete does.
The ideal section is balanced, with both the steel and concrete reaching their maximum strength at the same time.
Stress vs strain curves can be used to determine the yield strength, ultimate strength, and modulus of elasticity of a material.
