A hollow box beam has cross section shown above (a - 100 mm). If the largest internal bending moment present inside the beam is M - 20 kN-m, determine the smallest allowable thickness, t. of the cross section before vielding occurs in the ASTM A-36 structural steel beam (0,- 250 MPa) 15.08 mm 7.54 mm 12.63 mm 3.34 mm none of these answers 6.52 mm 9.21 mm 8.88 mm
