Let's clarify the relationship between physical rotation of an element and rotation on Mohr's circle: **On Mohr's Circle:** - **A counterclockwise rotation of θ on the physical element** corresponds to a **2θ clockwise rotation on Mohr's circle**. - **A clockwise rotation of θ on the physical element** corresponds to a **2θ counterclockwise rotation on Mohr's circle**. **Therefore, the correct statement is:** > **Rotation θ on the element = Rotation 2θ on the circle in the opposite direction** Let's match your options: 1. **Rotation θ on the element, Rotation 2θ on the circle in the opposite direction** ✔️ **This is correct.** 2. Rotation on the element, Rotation 0 on the circle in the same direction ❌ 3. Rotation 2θ on the element, Rotation 0 on the circle in the same direction ❌ 4. Rotation θ on the element, Rotation 2θ on the circle in the same direction ❌ **Correct answer:** **Rotation θ on the element, Rotation 2θ on the circle in the opposite direction**
