Z = 13*100mm PROBLEM: A thin-walled cantilever beam of unsymmetrical cross-section is subjected to a uniform distributed load was shown in the figure below. The wall thickness t can be assumed to be very small in comparison with hin calculating the sectional properties. Determine the stress distribution on the cross section and the position of the neutral axis. Find the deflection of the beam at the cross section. Use:w=0.8N/mm: L = 1500 mm; h = 80 mm: t= 2 mm:...
A beam is constructed with an I-section. The dimensions of the cross-section as well as its simplified wireframe/median-line model are shown below, where the symbols, O and , represent the centroid and shear center of the I-section, respectively. Assume the flange and web thicknesses (/f./) are much b=B smaller than the width and height of the section (B.H) and define . Due to the double-symmetry of the cross-section, we have Q- O. As shown in the figures, the cross section...
