To determine the vertical component at point D, we will need to analyze the forces acting at that point, especially in the context of equilibrium. Based on the diagram, it appears to be a structure with forces acting at different angles, and we can utilize trigonometry to resolve forces into their components.

### Assumptions:
1. The angle at D is given as \(41.41^\circ\), indicating that force at D is inclined.
2. The structure appears symmetric, implying possible equilibrium conditions (sum of vertical and horizontal forces equals zero).

#### Steps:
1. **Determine force direction at D:**
   If there is a force acting along the line from D to C, the vertical component of this force will be calculated using the sine of the angle at D.

   Let's call the total force at D, \( F_D \).

   \[
   F_{D_y} = F_D \cdot \sin(41.41^\circ)
   \]

2. **Analyze moments or forces:**
   We may need additional information such as external forces, the reaction at A, or moments acting on the structure. Based on the sketch, it seems like a loaded beam or arch structure, and equilibrium equations (sum of forces in x, y, and moments) can provide insights into the exact force at D.

   However, to proceed further, I'd need to know the total load applied to the structure or more boundary conditions.

Would you like to provide more information on the forces acting on the structure, or should I continue with equilibrium analysis assuming basic principles? Let me know if you'd like further clarification.
