Extracted text: Installed appointment of a beam made of a U profile in the figure Find the length c of the overhangs so that it can move. Of the material Safety stress (oç) emn = 50 N / mm2 for tensile and compression conditions, (ob) emn = 80N / mm2. Support spacing of the beam L = 6 m, cross section tape a = 210 mm, b = 150 mm and etc. t = 40 mm. The loading condition is P = 30 kN and q0 = 40 kN / m B (Kesit)
