Complete Solution, Please. Thank you!

The bearing type connection $($w$/$A$325$X $-$ M$22$ bolts$)$ shown is subjected to a service load $P.$ The thickness of the upper and

lower plates is $12\mathrm{.}7mm$ while the thickness of the middle plate is $19\mathrm{.}05mm.$ The values of $s_1$ and $s_2$ are such that tearout is not a concem. Use ASD. The material strengths of the plates

are $F_y=248$MPa and $F_u=400$MPa.

Find the required value of $s_2.$
