For the giver Frame. find the minimum thickness tein $(mm)$ of the bars of Member BD$,47)$ end decimal place, if the Maximum allowable Tensile stress is ${}_{\text{r}\text{a}\text{n}}=300$MPa and Maximur allowable Compressive stress is ${}_c$als$=250$MPa.

Force $P=50kN$

$-$Two bars

${}_1=s00k\frac{r}{h}$

$=300000kN{m}^2$

${}_n=\frac{p}{A}=$
