Question
![### Item 12
A 1.05-m-long rod of negligible weight is supported at its ends by wires \(A\) and \(B\) of equal length (the figure [Figure 1]). The cross-sectional area of \(A\) is 2.37 \( \text{mm}^2 \) and that of \(B\) is 4.44 \( \text{mm}^2 \). Young's modulus for wire \(A\) is \(2.40 \times 10^{11} \, \text{Pa}\); that for \(B\) is \(1.10 \times 10^{11} \, \text{Pa}\).
**Part A**
At what point along the rod should a weight \(w\) be suspended to produce equal stresses in \(A\) and \(B\)?
Express your answer in meters.
\[ d = \quad \text{m from wire } A \]
*Submit*
*Incorrect; Try Again; 4 attempts remaining*
**Part B**
At what point along the rod should a weight \(w\) be suspended to produce equal strains in \(A\) and \(B\)?
Express your answer in meters.
\[ d = \quad \text{m from wire } A \]

**Figure**
: A schematic diagram showing a horizontal rod, 1.05 meters in length, supported by two vertical wires, labeled \(A\) and \(B\), at each end of the rod. A weight \(w\) is suspended from a point along the rod.
**Diagram Explanation:**
The diagram illustrates a 1.05-meter-long horizontal rod with vertical wires \(A\) and \(B\) attached at its ends. The weight \(w\) is shown hanging from a point along the rod, indicating the need to determine the position \(d\) where the weight should be placed to achieve specific stress or strain conditions in the wires. This setup is used to explore concepts related to mechanical stress and strain in the context of engineering and physics.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fb2f5b0ad-df1d-48c6-a9a3-5338b8167143%2F5892851c-ad32-40d9-bdeb-9392eb6899b5%2F4lqtadi_processed.png&w=3840&q=75)
