QB3 TWO DIMENTIONAL STRAIN Three strain gauges were arranged in the form of a rectangular rosette and positioned on a test surface. The measured strains were as follows: E 1 = 200x 10-6 E 2 = 100 x 10-6 E 3 = 50 x 10-6 Determine a) the principal strains and the principle stresses b) the direction of the greater principal strain relative to gauge 1 and sketch the Mohr strain circle. Take the Young Modulus of Elasticity value to be E = 200 GN/m2 and Poisson's ratio i = 0.28. [9 marks] (a)5 marks b) 4marks]
