1.	Open cross sections have major part of material distributed(a) is not distributed(b) on the centroid(c) towards centroid(d) away from centroidThe question was asked at a job interview.This key question is from Factors affecting Lateral Stability in section Design of Beams of Design of Steel Structures
Answer» Right ANSWER is (d) away from centroid Easy explanation: In open cross sections ( I and channel sections), major part of material is DISTRIBUTED at the FLANGES, i.e. away from their CENTROIDS, to improve their resistance to in-plane bending STRESSES.
