This podcast is made by Ran Chen, who holds an EA license, Insurance and Securities licenses (Series 6, 63, 65), and the CFP® designation. He is passionate about opening access to high-quality exam preparation resources and helping learners prepare more effectively for professional certification exams. In this episode you will learn: - How to correctly plot the initial stress state on Mohr's Circle using the NCEES sign convention for shear stress. - The formulas for calculating the circle's center (average normal stress) and its radius (maximum in-plane shear stress). - How to determine the principal stresses, which are the maximum and minimum normal stresses, directly from the circle's geometry. - The application of the superposition principle for combined loading problems to find the initial stresses needed for Mohr's Circle. - The critical relationship that a rotation of theta on a stress element corresponds to a rotation of 2-theta on Mohr's Circle.
