Figure 4 shows a cross section (end view) of a steel beam with thickness T and dimensions V and H. (a) Determine the second moment of area (mm) about the x axis (i.e., Ix) that passes through the base. The actual values of T, V, and H are not given. Express Ix in terms of (T, V, and H). Show all your workings. (35 marks) (b) Develop an excel spreadsheet to calculate Ix for your chosen values of V (T and H should be kept constant). Present your results using a table and a figure. (35 marks) HINT: Same as A1 and A2, select 10 reasonable numbers of V. Present your results using a table and a figure, which must be presented in the submitted PDF. Zero mark will be given without presenting figure and table in the submitted PDF. (c) Discuss the results in part (b) and write a conclusion.
