Question

On a Mohr’s circle, any point on the circle represents:

• A. Axial stress only
• B. Pure shear
• C. Stress on some inclined plane
• D. Principal stress

Hint:

In Mohr's Circle, each point on the circle corresponds to the normal and shear stresses on a particular inclined plane. It is a powerful tool for visualizing and calculating stress transformations.

Answer 1

The Correct Option is C

Mohr's Circle is a graphical method used in the field of mechanics of materials to represent the state of stress at a point in a material. The circle is drawn in a two-dimensional stress space, where the x-axis represents normal stress and the y-axis represents shear stress.
Each point on Mohr's circle represents the stress state on a particular inclined plane within the material. Specifically:
- The points on the circle represent the normal and shear stresses on various planes inclined at different angles.
- The stress values correspond to the stresses experienced on these inclined planes, not just the axial stress or principal stress.
Thus, any point on Mohr’s circle corresponds to the stresses acting on some inclined plane at a specific angle, which is why the correct answer is Stress on some inclined plane.
Therefore, the correct answer is: Stress on some inclined plane.
