Question $5(0\mathrm{.}5$ points$)$

Determine the stresses at the locations pointed by the arrows if stress fringe value is $22k\frac{N}{m}$ and thickness is $8$ mm $?$ The specimen is subjected to concentrated compressive loads at the ends of the vertical diameter. The zero order fringes are given in the image.
