Question

Transcribed Image Text:A single crystal of a metal is oriented for a tensile test such that its slip plane normal makes an angle of 65.8° with the tensile axis.
Three possible slip directions make angles of 30°, 48°, and 78° with the same tensile axis.
(a) Which of these three slip directions is most favored?
i
(b) If plastic deformation begins at a tensile stress of 0.952 MPa (138.1 psi), determine the critical resolved shear stress for this metal.
i
