A beam is subjected to equal bending moments, as shown in Figure 1 . The crosssectional dimensions of the beam are shown. Determine: (a) the centroid location, the moment of inertia about the axis, and the controlling section modulus about the axis. (b) the bending stress at point . State whether the normal stress at is tension or compression. (c) the maximum bending stress produced in the cross section. State whether the stress is tension or compression. Figure 1: Beam and its cross-sectional dimensions
Expert Answer
Solution: Given the Bending moment, (a) the centroid location, the moment of inertia about the z-axis, and the controlling section modulus about the z-axiscentroid location, (from the bottom of the section)Total area, the moment of inertia about the z-axis,
