Problem $5(10$ points$)$

Split$-$tension tests are performed on two $4\mathrm{.}08\mathrm{.}0in.$ cylinder specimen. The samples fail at loads of $16500lb$ and $17150lb.$

Calculate the average split tensile strength of this concrete to the nearest $1.$

Estimate the compressive strength of this concrete based on the calculated split$-$tensile strength to the nearest $10$ psi.
