The force-deflection data from Example 1.3.1 for the cantilever beam shown in Figure 1.3.1 is given in the following table.

\begin{array}{l|lllllllll}\text{Force}f( lb ) & 0 & 100 & 200 & 300 & 400 & 500 & 600 & 700 & 800 \\\hline \text{Deflection}x \text{(in.)}& 0 & 0.15 & 0.23 & 0.35 & 0.37 & 0.5 & 0.57 & 0.68 & 0.77\end{array}

Use MATLAB to obtain a linear relation between x and f , estimate the stiffness k of the beam, and evaluate the quality of the fit.
