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? O (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 MPa

Calculate the viscosity of oxygen at 350 K and 1 atm pressure using equation 7.12 on page 90 of the text (also found in the PowerPoint slides).and compare with the value in Appendix I.

An acetal polymer block is fixed to the rigid plates at its top and bottom surfaces. If the top plate displaces 5 mm horizontally when it is subjected to a horizontal force P = 2 kN, determine the shear modulus of the polymer. The width of the block is 100 mm. Assume that the polymer is linearly elastic and use small angle %3D analysis.

If the maximum force one bolt can withstand is 32505 lbf, how many bolts can be removed from the pressure vessel at the given conditions before the end cap blows off?
