A beam is undergoing pure bending as shown in the figure. The stress (π)-strain (π) curve for the material is also given. The yield stress of the material is ππ. Which of the option(s) given represent(s) the bending stress distribution at cross-section AA after plastic yielding?
Which of the plot(s) shown is/are valid Mohrβs circle representations of a plane stress state in a material? (The center of each circle is indicated by O.)
A beam of length πΏ is loaded in the π₯π¦ βplane by a uniformly distributed load, and by a concentrated tip load parallel to the π§ βaxis, as shown in the figure. The resulting bending moment distributions about the π¦ and the π§ axes are denoted by ππ¦ and ππ§ , respectively.
Which one of the options given depicts qualitatively CORRECT variations of ππ¦ and ππ§ along the length of the beam?
