A single crystal of a metal is oriented for a tensile test such that its slip plane normal makes an angle of 66.4° 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? (b) If plastic deformation begins at a tensile stress of 2.5 MPa (355 psi), determine the critical resolved shear stress for zinc.

This is a characteristic of the elements in the periodic table that shows a pattern. it may increase or decrease across or down the table.

What is the polyatamic ion of borate

Look at the spectrums of a star moving towards earth and a motionless star. which of these is a correct inference that can be draw from the observation of the two spectrums? (2 points) the spectrum of a motionless star is difficult to be viewed separately using oridinary telescopes. the spectrum of a motionless star is identical to the spectrum of a star which moves towards earth. the spectrum of a star shifts towards the red region when the star moves towards earth. the spectrum of a star shifts towards the blue region when the star moves towards earth.
