Problem $6)$ consider a stabilizer bar $($anti roll bar$)$ connected to solid axle.

If $=21\mathrm{.}0$ deg, $b=70mm,c=460mm,E=200$GPa,$v=0\mathrm{.}3,K_t=22\mathrm{.}910Nm\frac{m}{r}ad,\frac{L}{2}=550mm,$

$a=250mm\frac{,}{{?}_{\frac{?}{?}}}A=75mm$

Determine: a$)$ Maximum bending stress

b$)$ The active length
