SUMMARY
The discussion centers on the interpretation of Mohr's Circle in relation to strain and stress. It clarifies that in the context of mechanics of materials, the radius of Mohr's Circle represents the maximum shear strain, while the application lab context may refer to the maximum strain divided by two. The confusion arises from the different axes used in plotting Mohr's Circle, where one uses normal strain and shear strain, while the other uses shear stress and normal stress. The correct equations for normal and shear strain on a specified plane are derived from the principal strains in the x and y directions.
