Three (3) strain gauges are fixed on the surface of a structure at point A in the respective directions as shown in Figure Q2. When the structure is loaded the readings of the gauges are 200. 350 and -100 along the directions of x, a and b, respectively. &=-100 70 130 Figure Q2 = 350 = 200 a) Determine the strains values in the x-y directions and draw the corresponding strain element. (2 marks) b) Determine the principal strain and draw the corresponding strain element. (3 marks) c) Determine the maximum shear strain and draw the corresponding strain element. (2 marks) d) If the material has E-208 GPa and v-0.28, determine the magnitude of the Principal Stresses and draw the corresponding stress element. (2 marks) e) Give your comment, without calculation on what would happen to the maximum principal strain if the material is changed to copper (E = 110 GPa)?
