QUESTION 3 [Shear Stresses in Wide-Flange Beam][28 points] A simply supported I-beam (see Figure Q3) has a span of \( 4 \mathrm{~m} \) and is subjected to a load of \( 90 \mathrm{KN} \) at midspan. The flanges are \( 100 \mathrm{~mm} \) wide and \( 15 \mathrm{~mm} \) thick. The overall depth is \( 175 \mathrm{~mm} \) and the web is \( 10 \mathrm{~mm} \) thick. 3.1 Plot the shear stress distribution diagram at any section, due to the shear force only. [18] 3.2 Calculate the percentage of the shear force that is carried by the web of the beam. [10]
