- 2. A single crystal of aluminum is oriented for a tensile test such that its slip plane normal makes an angle of 28.1° with the tensile axis. Three possible slip directions make angles of 62.4°, 72.0°, and 81.1° with the same tensile axis. (a) Which of these three slip directions is most favored? (b) If plastic deformation begins at a tensile stress of σ x = 1.95 MPa (280 psi), determine the critical resolved shear stress for aluminium. (c) If this single crystalspecimen is loaded under the new stress state: σ x =1.2 MPa σ y = -0.8 MPa, and τ xy = 0.6 MPa, howmuch is the resolve the shear stress along the most favored slip direction?arrow_forwardPlease explain how to do each part and tell me if my drawing is correct. thank youarrow_forward4.
