Problem:

Link $2$ is $25$ mm wide, has a $12$ mm $-$diameter bearings at the ends, and is cut from low$-$carbon steel bar stock having a minimum yield strength of $165$ MPa $.$ The end$-$condition constants are $C=1$ and $C=1\mathrm{.}2$ for buckling in and out of the plane of the drawing respectively. Use a design factor of $n=4,$ find suitable thickness for the link. $E=205$GPa.

$t=10\mathrm{.}5mm$
