Tutorial questions on shear stresses in beams subjected to non-uniform bending. Question One A hollow aluminum box beam has the square cross section shown in the figure. Calculate the maximum and minimum shear stresses Tmax and Tmin in the webs of the beam due to a shear force V = 125 kN 25 mm -300 mm- 25 mm Question Two The T-beam shown in the figure has cross sectional dimensions as follows: b = 210 mm, t= 16 mm, h = 300 and h₁ = 280. The beam is subjected to a shear force, V = 68 kN. Determine the maximum shear stress Tmax in the web of the beam. hi h C I
