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.

Which best describes why nh4+ can form an ionic bond with cl-?

Calculate the estimated density of each ball. use the formula d = m/v where d is the density, m is the mass, and v is the volume. record your calculations in table a of your student guide. given that the density of water is 1.0 g/cm3, make a prediction about whether each ball will float in water. record your prediction in table a. what is the estimated density of the table tennis ball? record your answer to the nearest hundredth
