Problem 8.5. Thin-walled “Box-Z” shaped cross-section beam A cantilevered beam of length L is constructed with the thin-walled cross-section shown in fig. 8.15. A concentrated load, P, is applied at the tip of the beam and acts along axis ¯?3. (1) Determine the location of the centroid. (2) Find the centroidal bending stiffnesses. (3) Determine the axial stress acting in the root section at points A and B. (4) Determine the vertical and horizontal components of the deflection at the tip using the given centroidal axes shown in the figure. Use b = c = a/2.8.2 Bending of thin-walled beams Fig. 8.15.
