Link $AB,$ of width $b=50mm$ and thickness $t=6mm,$ is used to Support the end of a horizontal beam. Knowing that the average normal stress in the link is $-140$ MPa $,$ and that the average shearing stress in each of the two pins is $80$ MPa $,$ determine :

$(a)$ the diameter $d$ of the pins,

$($b$)$ the average bearing stress in the link,

$($c$)$ if the plate thickness t is thicker than $6$ mm $,$ justify what will be happened of diameter $d$ of the pins and bearing stress in the link

ANSWER:$[($a$)25\mathrm{.}9$mm$,($b$)271$ MPa$]$
