Question
Question below. Thanks! Do the best you can - it's not hard. I did it already and just want to compare with some individuals.
The cross section shown in Figure 1 is subjected to a bending moment M2 = 5 kN-m. Ail the dimensions given on the figure are in millimeters. Find the location of the centroid C of the cross section. Express the location as horizontal and vertical distances from the left uppermost point A. For the cross section shown, calculate the moments of inertia Iyy and Izz as well as the product of inertia Iyz, where the y- and z-axes pass through the centroid C as shown. Find the neutral axis of the cross section. Based on the inclination of the neutral axis, do you expect the bending stress at the left uppermost point A to be tensile or compressive? Based on the inclination of the neutral axis, do you expect the bending stress at the right lowermost point B to be tensile or compressive? Explain, without actually computing the stresses at those points. Calculate the bending stress at point A, and the bending stress sigmaxx(B) at point B. Locate the point E that experiences the maximum tensile stress on the cross section, and compute the value sigmaxx(E) of the maximum tensile stress there. Locate the point D that experiences the maximum compressive stress on the cross section, and compute the value sigmaxx(D) of the maximum compressive stress there. Figure 1
