1. The problem statement, all variables and given/known data
a) This steel beam has a quadratic crosssection (A=100mm2). The force F is 10 kN. Calculate the stress in the rod and show that this stress does not exceed the yield strength of the steel. 2. The attempt at a solution a) [tex]\sigma = \frac{10000N}{0.0001m^2}=100 MPa[/tex] I guess this is right? I'm not sure what the yield strength is. Can I calculate it from the given formulas?

The result is okay, but note that [MPa] = [N/mm^2], and not [N/m^2], i.e. you didn't need to convert A into [m^2]. I'm not sure what the expressions in the image mean  are you given a yield strength for steel?

Thanks for replying.
No, nothing else is given. It is a socalled Failure Assessment Diagram (FAD).
