Q5. The I-beam shown in Figure 25 is subjected to a shearing force F of 10kN. The beam has an area, A = 9.4cm2, and second moment of area, I = 220cm. (a) Proof that the transverse shear stress t on the web at distance y from the neutral axis can be calculated using the following equation: F (20.95 -0.175y) 77 [6 marks] T (b)Calculate the value of transverse shear stress at the neutral axis and at the top of the web. [6 marks] (c) Compare the transverse shear stresses calculated in (b) with the average stress on the assumption of uniform distribution over the web. [4 marks] (d) Calculate the percentage of shear force is carried by the web? [5 marks] (e) Discuss your answer for (d) above. [4 marks] 5cm 0.55cm y 12cm Y... Neutral axis I II 0.35cm (Figure not to scale) Figure 25 [Total 25 marks]
