6. The material of the following cross-section is linear elastic - perfectly plastic and is able to resist both tension and compression. a) The cross-section is loaded with an eccentric compressive force F. The hatched domain shows the kern of the cross-section. Draw the diagram of normal stresses as well as the neutral axis for both cases! (The points of section are in the elastic state.) F y z b) Define the plastic limit (plastic load-bearing capacity) of a cross-section under bending! Draw the diagram of normal stresses if the cross-section is loaded by a moment equal to its plastic limit. Indicate the yield stress! Mpl
