Q2. Figure Q2 shows isochromatic fringes on an aluminium plate (E = 69 GPa, v = 0.31) with a hole, obtained during the Photoelasticity demo (see video on Learn). Using the material f-value and fringe order correction table provided in the corresponding lab: a) Determine the maximum shear stress and the tangential stress (tangent to the edge of the hole) at point A in Figure 2. (Note: Ignore the arrow, which points to the red spot for comparison with strain gauges). [5 marks] A
