Two members that read comfortably below yield and would still fail. A 10 m UB 406 x 178 x 60 with no lateral restraint carries 15 kN/m: 188 kN m at midspan, about half its yield stress, yet its elastic critical moment for lateral-torsional buckling is about 108 kN m. Beside it, an 8 m pin-ended UC 152 x 152 x 37 strut carries 400 kN: 85 MPa, a quarter of yield, yet its Euler load about the minor axis is about 229 kN.
