Homework #$6($due $9/16)$

This sieve analysis for #$8$ aggregate shows that it is mostly $\frac{3}{8}$ inch gravel. It's

called open graded. If it instead contained a range of particle sizes, it would be called

well graded.

Triaxial Test Data

Use a spreadsheet and Equation $(6\mathrm{.}17)$ to plot $p$ and $q.$ Find the slope of the best fit

line. Use Equation $(6\mathrm{.}19)$ to find the friction angle $$ of this #$8$ aggregate.
