A rosette consisting of 3 gages forming, respectively, angles of 0., 0 and & with the x-axis is attached to the free surface of machine components made of material with a given Poisson's ratio v and Modulus of elasticity E as shown in Fig. 6 and Fig. 7. Take note that strain values given above are the gage readings and not principal strains. 25 mm 250 mm 3 75 mm 75 mm Fig. 6: A rosette mounted on a machine part with v = 0.3 and E - 200GPa. Gage readings are: 61 - -75 x 10* mm/mm, - 300 x 10* mm/mm - 250 x 10 mm/mm
e. Draw 3-dimensional Mohr diagram and indicate the points X (given state of strains), center, 61, 62, 63, and Youx together with their coordinate values. Also indicate the orientation of Yes and orientation of the principal plane (both measured from given state of strains (point X)). f. Normal stress and shear stress components, Ox, Gy, 6, and Try. g. Magnitude and orientation of the maximum shear stress, Tmax (determine the orientation in degrees, measured from given state of stresses). h. Principal stresses, 01, 02, and o;. i. Orientation of the principal stress plane (determine the orientation in degrees, measured from given state of stresses). Draw 3-dimensional Mohr diagram and indicate the points X (given state of stresses), center, 01. 02, 01, and Tmax together with their coordinate values. Also indicate the orientation of Tmax and orientation of the principal plane (both measured from given state of strains (point X)).
