Answer» CORRECT choice is (b) for torsionally SIMPLE supports the moment coefficient is less than UNITY Easy explanation: The moment coefficient accounts for the effect of DIFFERENTIAL moment gradient on lateral torsional buckling and depends on type of loading. For torsionally simple supports the moment coefficient is greater than or equal to unity.
