Two channels having a cross section shown carries a tensile load. It has a length of $9$ m and has one line of three $22$ mmo bolts in each channel flange. The center of the bolt holes are $44\mathrm{.}50$ mm from the back of the channel. Use A$36$ steel.Properties of C$200$ x $45$are A $=5690$ mm$2,$ d $=300$ mm$,$ bf $=80\mathrm{.}52$ mm$,$ tf $=12\mathrm{.}73$ mm$,$ tw $=12\mathrm{.}95$mm$,$ rx $=108\mathrm{.}97$ mm$,$ ry $=19\mathrm{.}38$ mm$,$ x $=17\mathrm{.}12$mm$,$ Ix $=67\mathrm{.}4(10^6)$ mm$",$ and ly $=2\mathrm{.}14(10^6)$ mm$*$Compute the capacity of the tension member neglecting the effect of the plates. Calculate the slenderness ratio of the section. Determine the dimension of the plates.
