A student wants to measure the strain at a particular point K on a loaded specimen, so she affixes a 45 strain rosette at point K and obtains the following results: A = 380 rad B = 250 rad c = 400 rad After packing up and going home to analyse her results, she realises that the strain rosette was misaligned by 0 degrees CW (where a negative e corresponds to CCW) from the x-y axes-ie. Gauge C is not parallel with the x-axis and is instead parallel with a different x' axis that is rotated by 0 degreeswhere: 0 = 18 deg Instead of replacing the rosette and retaking measurements, the student realises she can use what she learned in ENGG2400 to find the strains she's interested in. 45 45 a a) Draw a diagram of the situation, showing both the x-y axes and the strain rosette. (0.5 marks) b) Calculate Exx, Eyy and Yxy. (2 marks) c) Calculate the maximum in-plane shear strain and the associated average normal strain. (2 marks) x
