The steel beam of uniform T-section shown in Figure Q3(b) is simply supported over a length of 2.5 m and is subjected to a concentrated load W at mid-span. The yield stress of steel is 300 MNm-2 (in tension and in compression). (b) 100mm 10 mm W 10 mm 110 R R Figure Q3(b): T- Section Structural Beam (i) Determine the position of the neutral axis for elastic bending. (ii) Calculate the second moment of area I about the neutral axis. (iii) Determine the value of W when yielding is about to commence in the section, i.e. at onset of yielding, at mid-span.
