ME 80 Professor Levenston Instructional Objectives : Stress, strain and axial deformation By the end of this section (roughly 3 classes), you should be able to: Define the terms stress and strain; Explain the differences between normal and shear stresses and strains; Describe the physical meaning of the elastic (Young’s) modulus, shear modulus and Poisson’s ratio; Identify the yield stress, ultimate stress and failure stress if given a tensile stress-strain curve; Define the terms allowable stress and factor of safety; Describe the general relationships between force, stress, strain and deformation in axially
