**Table Overview: Spring Specifications**

| Property         | Value      |
|------------------|------------|
| Free length      | 55 mm      |
| End condition    | Plain      |
| Total coils      | 13         |
| Wire diameter    | 2.2 mm     |
| Spring index     | 11         |
| Material         | Music wire |
| Shear modulus (G) | 80 GPa    |

**Explanation:**

- **Free length**: The unstressed length of the spring is 55 millimeters.
- **End condition**: The spring has a plain end condition.
- **Total coils**: There are 13 coils in the spring.
- **Wire diameter**: The diameter of the wire is 2.2 millimeters.
- **Spring index**: The ratio of the coil diameter to the wire diameter is 11.
- **Material**: The spring is made of music wire, known for its high tensile strength.
- **Shear modulus (G)**: A measure of the material's rigidity is 80 gigapascals (GPa).
