Question
Consider the following statements for a beam of rectangular cross-section and uniform flexural rigidity EI subjected to pure bending:
1. The bending stresses have the maximum magnitude at the top and bottom of the cross-section.
2. The bending stresses vary linearly through the depth of the cross-section.
3. The bending stresses vary parabolically through the depth of the cross-section.
Which of these statements is/are correct?
