Question
### Problem Statement A steel beam has the I-shaped cross-section shown. Knowing the steel has an allowable normal stress of 150 MPa, determine the maximum bending moment that can be applied to the beam if: (a) the moment is applied about the y-axis, (b) the moment is applied about the z-axis. ### Diagram Explanation The accompanying diagram illustrates an I-shaped cross-section. The dimensions are detailed as follows: - **Height Dimensions:** - The total height of the I-section is 140 mm. - The flange thickness at the top and bottom is 30 mm each. - The web (central vertical section) is 80 mm in height. - **Width Dimensions:** - The width of the flanges is 120 mm. - The width of the web is 40 mm. - The diagram includes coordinate axes, with the vertical axis labeled as y, and the horizontal axis labeled as z. The center of the section is marked as point C.
