1. A solid is deformed under "plane stress" conditions. Strain gauges mounted on the element give the following readings: Gauge 1: 1.0 x 10-3 mm/mm Gauge 2: 0.3 x 10-3 mm/mm Gauge 3: -1.2 x 10 mm/mmy G G21 0 = 40 i) Determine the shear strain in the xy coordinate system. ii) Represent the strain conditions with a Mohr's circle of strain (i.e. Find and demonstrate coordinates of x, y, and x' points on the circle). iii) Determine the stresses in the solid (oxx, Gyy, Txy), assuming elastic behaviour. Assume E = 210000 MPa and v=0.25.
