A blacksmith fixes iron ring on the rim of the wooden wheel of a bullock cart. The diameter of the rim and the ring are `5.243 m` and `5.231 m` respectively at `27^(@)C`. To what temperature should the ring be heated so as to fit the rim of the wheel ? Coefficient of linear expansion of iron =` 1.20 xx 10^(-5) K^(-1)`

Explanation

To solve the problem, we need to determine the temperature to which the iron ring should be heated in order to fit onto the rim of the wooden wheel. We will use the formula for linear expansion.

### Step-by-Step Solution:

1. **Identify the Given Values:**
- Diameter of the rim (D_rim) = 5.243 m
- Diameter of the ring (D_ring) = 5.231 m
- Initial temperature (T1) = 27°C
