Maximum shear stress in Mohr's circle is equal to
- A. Radius of circle
- B. Diameter of circle
- C. Centre of circle from y-axis
- D. Chord of circle
Answer: A. Radius of circle
Explanation: The maximum shear stress in Mohr's circle corresponds to the top or bottom points of the circle, which is exactly equal to the radius of the Mohr's circle: $\tau_{max} = R = \frac{\sigma_{1}-\sigma_{2}}{2}$.
