Express your answer in psi to three significant figures. Include the sign of the stress in your answer. ![]() Part C - Maximum bending stress Determine the absolute maximum bending stress in the section if it is subjected to an internal moment of 535 ft lb around the z-axis. View Available Hint(s) PHA ? I= Value Units Submit What is the moment of inertia of the section for bending around the z-axis? Express your answer to three significant figures and include the appropriate units. Part B - Calculate the moment of inertia Once the position of the centroid is known, the moment of inertia can be calculated. Design Examples 1 through 4 illustrate the application of Flexure 1 to Flexure 4. 1-2 for selected values of t listed in the design aids. (1-11), where the -factor is obtained from Fig. View Available Hint(s) ? UA 7 M Value Units Flexure 1 through Flexure 4 contains Kn values computed by Eq. What is the distance T' from the bottom of the section to the centroid? (Figure 3) Express your answer with appropriate units to three significant figures. Figure < 1 of 3 Part A - Locate the centroid Since the widths of the two flanges are not the same, the centroid is not readily apparent. The beam is subjected to a moment so that the internal moment on the section is about the z-axis. The neutral axis of the section nasses through the centroid My In Consider an l-beam section with unequal flanges (Figure 2), where w1 = 9 in., h = 6.2 in. ![]() ![]() It can also be written in terms of the vertical distance from the neutral axis, y, O = each equation, I is the moment of inertia of the cross- sectional area about the same neutral axis. Transcribed image text: The Flexure Formula 1 of 9 > Mc, where c is the perpendicular distance 11 Review Mc omax = from the neutral axis to the farthest point in the section.
