2a. The delta strain gauge rosette shown in Figure 2a is attached to a structural component and measures the following strains: e, = 775x106, ɛz = 415×106, ɛ̟ =-515x10°. Determine the principal strain and principal stress components in both magnitude and direction given that the structure has a Young's Modulus of E = 200×10² N/mm? and Poisson's ratio of v = 0.3 . Show the directions of the principal stresses on a properly oriented stress element relative to the x,y coordinate system. 60° 60° 60° Figure 2a
