고체역학 (Gere) — Stresses in Beams (Basic Topics): Problem 5.10-11

5.10-11 A hollow aluminum box beam has the square cross section shown in the figure. Calculate the maximum and minimum shear stresses \(\tau_{max}\) and \(\tau_{min}\) in the webs of the beam due to a shear force \(V = 125\text{ kN}\). Dimensions from figure (Problem 5.10-11): Outer side length: \(300\text{ mm}\) Wall thickness (top and bottom flanges): \(25\text{ mm}\) Wall thickness (side webs): \(25\text{ mm}\) Shear force \(V = 125\text{ kN}\)
