The problem asks to determine the three forces acting on the plate that are equivalent to the resultant force \( R = 210 \, \text{kN} \). The three forces \( T_1 \), \( T_2 \), and \( T_3 \) act in different directions, and their vectors can be expressed in terms of their components along the \( x \), \( y \), and \( z \)-axes. Here's a step-by-step outline of the solution approach:

### Step 1: Identify Coordinates of Points
From the diagram:
- The plate is in the \( xy \)-plane.
- \( T_1 \) acts from a point located at (1, 0, 0) and directed upwards.
- \( T_2 \) acts from a point at (3, 0, 0) in a diagonal direction.
- \( T_3 \) acts from (2, 2, 0) in another diagonal direction.

The forces' directions can be defined by their position vectors relative to the plate and the anchor point at the top, 6 m above the plate in the \( z \)-direction.

### Step 2: Write the Force Vectors
Let each of the force vectors \( T_1 \), \( T_2 \), and \( T_3 \) have components in the \( x \), \( y \), and \( z \) directions, denoted as:
- \( \mathbf{T}_1 = (T_{1x}, T_{1y}, T_{1z}) \)
- \( \mathbf{T}_2 = (T_{2x}, T_{2y}, T_{2z}) \)
- \( \mathbf{T}_3 = (T_{3x}, T_{3y}, T_{3z}) \)

### Step 3: Apply Equilibrium Equations
The resultant force \( R = 210 \, \text{kN} \) is distributed among the three forces, and the system is in equilibrium. Therefore, the sum of the components of \( T_1 \), \( T_2 \), and \( T_3 \) must equal the resultant force \( R \) in all directions.

1. \( \sum F_x = 0 \)
2. \( \sum F_y = 0 \)
3. \( \sum F_z = R \)

Using the geometry of the situation and the coordinates of the forces, each of these equations can be expressed in terms of the known distances.

### Step 4: Solve for Magnitudes of the Forces
Using the equilibrium equations and the geometric relationships (based on the distances given in the figure), solve for the magnitudes of the forces \( T_1 \), \( T_2 \), and \( T_3 \).
