Chapter 9, Problem 9.55P

Interpretation Introduction

Interpretation:

The equation of the tensile strength line is to be determined along with the SDAS value for the zero tensile strength. Also, it is to be stated if extrapolation of this line makes any sense or not.

Concept Introduction:

The slope-intercept form of a line is,

  $y=mx+c$ ....... (1)

Here, $m$ is the slope of the line and $c$ is the intercept.

Slope $\left(m\right)$ of a straight line is calculated as:

  $m=\frac{y_2-y_1}{x_2-x_1}$ ....... (2)
