Shear of Thin-Walled Beams (closed section) 3. A box girder has the singly symmetrical trapezoidal cross section shown below. It supports a vertical shear load of 1000 kN applied through its shear center and in a direction perpendicular to its parallel sides. Calculate the shear flow distribution and the maximum shear stress in the section. The thickness t of the upper flange is 8 mm, lower flange is 12 mm and the two inclined sides is 10 mm. 1000 kN...
Consider a cantilever beam (I section) subject to a torsional load, T, and the cross-section is assumed narrow in thickness (t) as represented in the figure below. Using the membrane analogy, please determine shear stress distribution in domain of I cross-section (using torsional equations and shear flow).

3. The beam, with symmetric cross-section about y (all thicknesses of 1 in) as shown, is subjected to an internal moment of M 480 kip.in and a shear force of V 340 kip. For this system, a) determine the location of the neutral axis, y (measured from the bottom of cross-section as shown) and the area moment of inertia, I about the neutral axis (NA or z-axis), the maximum compressive, (o,nax), and tensile, (Omax): normal stresses, and b) o kip....
