A 10 kg mass is attached to one end of a copper wire, 3m long and 1 mm in diameter. Calculate the lateral compression produced in it. (Possion's ration is 0.25and Young's modulus, of the metereal of the wire is modulus of the material of the wire is `12.5 xx 10^(10) N//m^(2))`.

Explanation

To solve the problem of calculating the lateral compression produced in a copper wire when a 10 kg mass is attached to it, we will follow these steps:

### Step 1: Gather Given Data
- Mass (m) = 10 kg
- Length of the wire (L) = 3 m
- Diameter of the wire (d) = 1 mm = 1 x 10^(-3) m
- Poisson's ratio (σ) = 0.25
- Young's modulus (Y) = 12.5 x 10^(10) N/m²
