QUESTION 4 The following state of strain has been determined on the surface of a machine part subjected to plane strain using a 60° strain rosette, where E= 210 GPa and v=0.3. Ea = -90μ Eb = -360μ &c = +170μ Determine: (a) The normal strains (Ex. Ey) and the shear strain Yxy- (3 marks) (b) The normal strain (₁) and the shear strain (y) on an inclined plane that is oriented 30⁰ counterclokwise from the x-axis. (4 marks) (c) The principal strains (Ep1, Ep2, Ep3) and the maximum shear strain (Ymax). (4 marks) (d) The normal stresses (n.) and shear stress (Tnt) in a plane counterclokwise from the x axis. oriented at 30° (4 marks)
