Part C - Shear strain along different axes Shear strain in an object is defined by the change in angle between two axes that lie within an object; it is, therefore, possible that shear strain may be present in a deformed object depending on the axes of interest. Consider the cubes below that are subjected to forces that deform them. In the undeformed state, the sets of axes XY, AB, PQ, and RS all are pairs of perpendicular axes. Which statement below accurately describes the relationship between the shear strains γXY, γAB, γPQ, and γRS?
