Please find both the stress for BOTH inner and outer surfaces at section B $-$ B$.$ The steel eyebolt shown in the figure is loaded with a force $F=350\mathrm{.}0N.$ The bolt is formed from wire of diameter $d=6\mathrm{.}00mm$ to a radius $R_i=12\mathrm{.}00mm$ in the eye and at the shank. Estimate the stresses at the inner and outer surfaces at section $B-B,$ located along the lines between the radius centers.

Determine the stress at the inner surface at section $B-B.$

The stress at the inner surface at section $B-B$ is $$ MPa $.$
