### Strain Analysis Using Mohr's Circle

#### Problem Statement
The state of strain at a point on a wrench has the following components:
- \( \varepsilon_x = 120 \times 10^{-6} \)
- \( \varepsilon_y = -180 \times 10^{-6} \)
- \( \gamma_{xy} = 150 \times 10^{-6} \)

#### Part A
**Objective:**
Use Mohr's circle to determine the maximum in-plane shear strain.

**Input Box:**
- You will see an input box where you can enter the maximum in-plane shear strain (\( \gamma_{\text{max}}^{\text{in-plane}} \)).

![Mohr's Circle input](#)
*Hint: Use Mohr's circle plotting to find the value accurately.*

#### Part B
**Objective:**
Specify the orientation of the element.

**Instructions:**
- Enter the orientation of the element in the provided input box.
- Ensure your answer includes the appropriate units.

![Orientation input](#)
*Hint: The orientation \((\theta_s)\) can be found from the angle on Mohr's circle, which relates to the physical plane angle.*
