Question

When is it appropriate to use Mohr’s Circle? When is it not applicable

Answer 1

‌1. Mohr's circle is often used in calculations relating to mechanical engineering for materials' strength, geotechnical engineering for strength of soils, and structural engineering for strength of built structures.
2‌. It is also used for calculating stresses in many planes by reducing them to vertical and horizontal components.
‌3. Mohr's circle can also be used to find the principal planes and the principal stresses in a graphical representation.
‌4. The Mohr circle can be applied to any symmetric 2x2 tensor matrix, including the strain and moment of inertia tensors.
‌5. Mohr's circle also used for the representation of both two- and three-dimensional stresses and a failure criterion based on the stress circle can be developed.
