### Understanding Moments in Physics

**Moment about Point \( D \), \( M_D \):**
\[ M_D = \text{(input box)} \, i + \text{(input box)} \, j + \text{(input box)} \, k \, \text{N} \cdot \text{m} \]

**Moment about Rod \( ED \), \( M_{ED} \):**
\[ M_{ED} = \text{(input box)} \, \text{N} \cdot \text{m} \, \text{(dropdown menu)} \]

This text provides input fields for calculating the moment about a point and a rod. Each vector component is represented by an axis (\( i, j, k \)) with units of Newton-meters (\( \text{N} \cdot \text{m} \)). There's also a dropdown menu selection for specifying direction as viewed from \( E \) towards \( D \).

For the bracket shown with the forces \( P = 650 \, \text{N} \) and \( Q = 0 \, \text{N} \), and distances \( a = 2.9 \, \text{m} \) and \( b = 1.5 \, \text{m} \), determine the moment about point \( D \) due to the force \( Q \) and the moment about rod \( ED \) due to the force \( Q \).

**Diagram Summary:**
- The diagram is a 3D representation of a bracket structure.
- Points \( A \), \( B \), \( C \), \( D \), \( E \), and \( O \) are labeled on the structure.
- Distances and dimensions are given: \( 0.6 \, \text{m} \), \( 0.75 \, \text{m} \), \( 2.25 \, \text{m} \) on the base; height from \( O \) to \( A \) is \( 2.9 \, \text{m} \).
- Forces \( P \) and \( Q \) are applied at point \( A \).
- Coordinate axes \( x \), \( y \), and \( z \) are shown in both diagrams.

**Graph/Diagram Explanation:**
- **Top Diagram:** Illustrates the 3D geometry of the bracket with force \( P \) shown acting downward at point \( A \).
- **Bottom Diagram:** Provides a colored 3D axis representation of the system. The colors indicate different directions for clarity, with a play button icon suggesting that it might link to an interactive model or animation.

This setup will aid in understanding the torque and force distribution across different points on the structure considering various applied forces and distances.
