SUMMARY
The discussion confirms that the equation for plotting a stress versus strain graph in the elastic region is correctly represented by the formula stress = strain * Young's modulus. The variables are defined as follows: stress (F/A) is the force per unit area, strain (dL/L) is the change in length divided by the original length, and Young's modulus serves as the proportionality constant. This relationship holds true within the elastic limit of materials.
