In the course of your internship at a development company you are asked to make a technicalrecommendation related to the optimum use of material for structural purposes. In this case you aregiven two types of timber/wood sections. The dimensions of the sections are shown in the followingFigure 1.150mm200mm50 mmFIGURE I1) Propose a composite "T" section beam that will give the maximum moment of Inertia (l) inhorizontal (or x-x).Hint:a) First determine the position of neutral axis (centroid) x-x of the composite. Thendetermine the distance of the individual centroid to the composite centroid.b) Calculate individual (I.)c) Calculate composite (I)

Two possibilities are there to make a "T" section from the given wood sections.
