Extension of Wire

Extension of Wire

### Formula

$$\Delta L=\frac{FL}{AY}$$

### Terminologies

- ΔL → Extension.

- F → Applied force.

- L → Length of wire.

- A → Cross-sectional area.

- Y → Young's modulus.

### Conditions / Special Cases

Extension increases with:

$$F,L$$

Extension decreases with:

$$A,Y$$

### Usage

- Used in wire deformation problems.
