Question details

uo2.32 Ih terms of psi 4. A large piece of annealed 4340 is subject to plane stress in which one stress is 200 MPa in compression. In order to achieve yielding (using the textbook inside front cover information), what must the tensile stress (MPa) be in the other plane direction. a. Assuming the maximum shear-stress-theory? b. Assuming the distortion-caerey thenn
