The beam shown in Figure Q1(a) has a cross-sectional area in the shape of I-beam, Figure Q1(b). Determine the maximum bending stress that occurs in the beam at section In order to increase its strength, it is proposed that two oak boards are added between its flanges as shown in Figure Q1(c). Determine the maximum normal stress in the beam for this case. Take Ewood 12 GPa, Est = 200GPa Based on the results from Q1(b), do you agree with the statement that adding wood to the beam flanges will increase the strength of the beam? State the reason. 20 mm 360 mm 20 mm Im a 200 mm (b) Neutral axis 20 mm 3900 N 2m (a) 20 mm 360 mm 20 mm Figure Q1: The beam 12 13 5 Neutral axis 20 mm 200 mm (c) GI + I AL'.
