MOHR'S CIRCLE PRACTICE PROBLEMS
To a person seeing Mohr's circle for the first time, it may seem long and involved. But with
practice under a variety of combinations of normal and shear stresses, you should be able to execute the 14 steps quickly and accurately.
Table 4-1 gives six sets of data (Example Problems 4-3 through 4-8) for normal and shear stresses in the x-y plane. You are advi.sed to complete the Mohr's circle for each before looking at the solutions in Figures 4-19 through 4-24. From the circle, determine the two principal stresses, the maximum shear stress, and the planes on which these stresses act. Then draw the given stress element, the principal stress element, and the maximum shear stress element, all oriented properly with respect to the x- and y- directions.
