Question
**Problem Statement:**

A 83.3-N backpack is hung from the middle of an aluminum wire, as shown in the diagram below. The temperature of the wire then drops by 15.4°C. Find the tension in the wire at the lower temperature. Assume that the distance between the supports does not change, and ignore any thermal stress.

**Diagram:**

- The diagram illustrates an aluminum wire with length \( L_0 \) suspended horizontally between two fixed supports.
- A backpack weighing 83.3 N is hung from the middle of this wire, causing a symmetrical sag.
- The distances from the points where the backpack is hung to each support are both labeled as 3.00 meters.

**Solution:**

- You are asked to calculate the tension in the wire after a temperature decrease of 15.4°C.
- The number provided for input is "710" with units selectable as Newtons (N).

Note: Calculating the tension involves understanding thermal expansion and the principles of physics related to forces in wires.
