The strains measured using a 45 strain rosette shown in figure are &p=400x10-6, &q=200x10-6 and &y=100x10-6. a) Find the principal strains and their directions. b) Maximum shear strains. c) Draw the Mohr's Circle. d) Find the principal stresses at the point. e) Determine the strains acting on an element that is oriented 120 clockwise with respect to the original element. E = 200 GPa, v = 0.3. Y Y 45 45 120 9 -X
