A vertically loaded bracket is attached to a column by three identical bolts ISO class $8\mathrm{.}8.$ The dimensions in mm and the load are as

described in the figure below. The bolts are to be installed preloaded to $70\%$ of their proof load and kmb $=2.$ Size the bolts for a

safety factor of $1\mathrm{.}5$ based on yield $($the SF is the same for the shear and tensile loading$).$ Conservatively assume that shear will be in

N$-$condition. $($Solve in SI$).$

$1)$ Compute both tensile, and shear loads on every bolt. $($X$.$X kN$)$

I$\text{'}$d really appreciate as much detail and explanations as possible.

Thank you!
