Please answer the following questions by referring to the below figure calculate the location of the centroid, the second moments and product of area for the cross-section if; • D = 67 mm • B = 41 mm t = 2.41 mm. From these, calculate the position and orientation of neutral axis for pure bending in the vertical plane (i.e. bending about a horizontal axis). Also calculate the directions of the principal second moments of area. Next, graph as scale diagram of the cross-section and plot the neutral axis on that diagram in the correct location and indicate the direction of deflection for the same conditions A A L Test beam Strain gauge W (a) Unsymmetrical cantilever beam with weight applied at the free end and at the "shear centre", so that there is no torsion induced. b a Section A-A Strain gauge 1 Strain gauge 3 B Strain gauge 2 D (b) Location of Huggenberger strain gauges Here is the previously referenced figure provided as necessary information to complete the question.
