The image you uploaded describes a static equilibrium problem involving a rope BAC supporting a load with a weight of 320 N. Forces \( Q \) and \( P \) hold the load in the position shown in the diagram, where the lengths of certain components are specified, such as \( BZ = 120 \, \text{mm} \) and \( CX = 120 \, \text{mm} \).

### Step-by-Step Solution:

1. **Coordinate System Setup:**
   - The point \( A \) represents where the ropes meet, and forces are applied at the points \( B \) and \( C \), which are positioned in space.
   - The force due to the weight of the object, \( W = 320 \, \text{N} \), acts downward along the \( z \)-axis.
   - The tension forces in the ropes \( AB \) and \( AC \) need to be resolved into components along the \( x \)-, \( y \)-, and \( z \)-axes.

2. **Geometric Information:**
   - The distances given are:
     - \( AB = \sqrt{130^2 + 120^2 + 400^2} = \sqrt{16900 + 14400 + 160000} \, \text{mm} \)
     - \( AC = \sqrt{240^2 + 120^2 + 400^2} = \sqrt{57600 + 14400 + 160000} \, \text{mm} \)
   - Convert these distances into meters for consistency (divide by 1000).

3. **Static Equilibrium:**
   Since the object is in static equilibrium, the sum of forces in each direction must be zero:
   - \( \sum F_x = 0 \)
   - \( \sum F_y = 0 \)
   - \( \sum F_z = 0 \)

4. **Force Components:**
   The tension forces in the cables \( AB \) and \( AC \) must be broken down into their components:
   - For rope \( AB \), the force components are \( P_x \), \( P_y \), and \( P_z \).
   - For rope \( AC \), the force components are \( Q_x \), \( Q_y \), and \( Q_z \).

5. **Equilibrium Equations:**
   Use the components to set up the system of equations:
   - \( P_x + Q_x = 0 \) (equilibrium in the \( x \)-direction)
   - \( P_y + Q_y = 0 \) (equilibrium in the \( y \)-direction)
   - \( P_z + Q_z + W = 0 \) (equilibrium in the \( z \)-direction)

By solving this system of equations, we can determine the magnitudes of forces \( P \) and \( Q \).
