Homework Statement
[PLAIN]http://img17.imageshack.us/img17/5112/ph2b.jpg [Broken]a) This steel beam has a quadratic cross-section (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.[PLAIN]http://img600.imageshack.us/img600/1163/phya.jpg [Broken]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?
