$Me={1\mathrm{.}14}^{**}{10}^{6}Nm$

$I={1\mathrm{.}066}^{**}{10}^{9}m{m}^4$

$b$ and $h$ as given in the model to the right, $b=320mm,h=430mm$

sigma $s=230**{10}^{6}Pa$

and the $E$ modulus is

$210**{10}^{9}Pa$

Q$1$: Determine how large the load $P$ e is when incipient plasticity occurs somewhere in the beam andindicat where in the beam this occurs$($In meter$).$ It happens when the largest moment somewhere in the beam amounts to Me $.$

Q$3$: determine the maximum shear stress in the beam.
