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

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

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

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 andindicate where in the beam this occurs. It happens when the largest moment somewhere in the beam amounts to Me$.$

Q$2$: determine the maximum shear stress in the beam.

Q$3$: Determine the load P s when the bearing capacity of the beam is fully utilized. What is the ratio between P s

when the beam collapses and P e at incipient plasticization.
