$1)$ A $12$ mm thick plate shown in is used as a tension member. The holes are punched for $20$ mm bolts. The damaged hole diameter is $4$ mm larger than the bolt$\mathrm{.}1.$ Determine the critical tensile fracture path for the plate by calculating the net width of the following paths.

A$.$ A$-$B$-$C$-$D

B$.$ A$-$B$-$C$-$E$-$F

C$.$ A$-$B$-$E$-$F

D$.$ A$-$B$-$C$-$E$-$D

$2)$ Determine the critical net area of the plate in mm$2$

$3)$ Determine the design tensile strength $($kN$)$of the plate based on critical net area. Use Fy $=248$ MPa and Fu $=400$ MPa and resistance factor of $0\mathrm{.}75.$
