### Required Information

**Rod AB** consists of two cylindrical portions, **AC** and **BC**, each with a cross-sectional area of $1820 \, \text{mm}^2$. Portion **AC** is made of a mild steel with $E = 200 \, \text{GPa}$ and $\sigma_y = 250 \, \text{MPa}$, and portion **CB** is made of a high-strength steel with $E = 200 \, \text{GPa}$ and $\sigma_y = 345 \, \text{MPa}$. The force $P$ is gradually increased from zero until the deformation of point **C** reaches a maximum value of $\delta_m = 0.3 \, \text{mm}$ and then decreased back to zero.

**NOTE:** This is a multi-part question. Once an answer is submitted, you will be unable to return to this part.

### Diagram Description

The diagram shows a vertical rod labeled **AB** with two segments, **AC** and **BC**. Each segment is marked as being 190 mm long. A force $P$ is applied downward at the point **C**.

### Task

**Determine the maximum value of $P$.**

The maximum value of $P$ is $\_\_\_\_\_$ kN.
