QUESTION 3 (20 marks) The state of stress at a point on the surface of a thin plate is as shown in figure Q3. The reading of the strain gauge, S, was 212 us when the stress, ox was 55 MPa. The strain gauge, S, was oriented at 30° to the positive x-direction. Determine the following: (a) Determine the Poisson's ratio using Hooke's law: G = (a) The magnitude of Gy (b) The principal strains I (c) The maximum in-plane shear strain on the plate Data: E = 200 GPa G = 80 GPa Figure Q3 S M E 2(1-v) I [2 marks] [8 marks] [8 marks] [2 marks]
