**Problem 6.120**

The composite beam is made of steel (A) bonded to brass (B) and has the cross section shown. It is subjected to a moment of \(M = 6 \text{ kN} \cdot \text{m}\). \(E_{\text{Br}} = 100 \text{ GPa}\), \(E_{\text{St}} = 200 \text{ GPa}\). (Figure 1)

**Figure Explanation**

The figure illustrates a composite beam with a cross-section composed of two bonded materials: steel (A) on the upper portion and brass (B) on the lower portion. The dimensions and orientation of the beam are detailed as follows:

- The height of the steel section is 50 mm.
- The height of the brass section is 200 mm.
- The base width of the beam (brass section) is 175 mm.
- A moment \(M\) is applied, causing bending, indicated around the z-axis such that the deformation is presented in the x-y plane.

The beam coordinates are defined such that:

- The x-axis runs horizontally along the width,
- The y-axis runs vertically along the height,
- The z-axis runs perpendicularly through the depth of the beam.

This setup is typically analyzed to understand stress distribution and deformation characteristics when subjected to the given moment and the interaction between the different material properties given by the Young's Modulus values (\(E_{\text{Br}} = 100\) GPa for Brass and \(E_{\text{St}} = 200\) GPa for Steel).
