Calculate the web in-plane bending buckling strength of a panel rib for: web thickness tw = 2mm web height bw = 40 mm effective modulus E = 8,044 N/mm2 effective Poisson's ratio v = 0.25 in-plane bending buckling constant kb = 24 for all edges simply supported Reduce the buckling constant by a factor of 10 for free edges Quote the value in MPa to one decimal place.

Please draw shear force diagram v(X) and bending moment diagram m(X)

Find the max shear stress in bending in the cross section below if Vmax = 10 kips. 10" Flange 2" Web 2" 8" Flange 2" 10" • Identify where in the cross section the max shear will occur. Determine the thickness of the cross-section at the location you wish to find shear stress. • Calculate the Ix for the shape (assume bending in the x with most basic beams). • Calculate Q by dividing the section into two pieces at the point you want shear stress. Select one of the pieces (either will work), I picked the top piece. Use the Shear Stress equation to determine the requested stress. Compare you answer: Max shear stress = at the center of the cross section.
