In the figure, find the length c of the overhangs so that the beam made of U profile can carry the loading safely. The safety stress (σç) emn = 50 N / mm2, (σb) emn = 80 N / mm2 for the tensile and compression condition of the material. The support range of the beam is L = 6 m, cross-section dimensions a = 210 mm, b = 150 mm and wall thickness t = 40 mm. The loading condition is P = 30 kN and q0 = 40 kN / m.

Extracted text: In the figure, find the length c of the overhangs so that the beam made of U profile can carry the loading safely. The safety stress for the tensile and compression condition of the material is (opull) safety = 50 N / mm, (gpress) safety = 80N/ mm². The support range of the beam is L = 6 m, cross-section dimensions a = 210 mm, b = 150 mm and wall thickness t = 40 mm. The loading condition is P = 30 kN and qo = 40 kN / m (Please solve in detail and according to engineering rules.) Material mechanics B
