1.	Which of the following is true?(a) point load causes less shear lag than uniform load(b) point load causes more shear lag than uniform load(c) point load causes half times the shear lag than uniform load(d) point load causes equal shear lag as uniform loadThe question was asked by my college professor while I was bunking the class.I'd like to ask this question from Design Strength of Laterally Supported Beams topic in portion Design of Beams of Design of Steel Structures
Answer» The CORRECT ANSWER is (B) point load causes more shear lag than uniform load The best I can EXPLAIN: The resultant stress DISTRIBUTION across flanges is non-uniform and is called shear lag. Point load causes more shear lag than uniform load.
