### Title: Determining Force and Line of Action for a Loaded Plate

#### Introduction
In this mechanical problem, we are tasked with analyzing a loaded plate on which four parallel forces are applied. Three of these forces are known, while the fourth force \( P \) and its line of action are to be determined. 

#### Problem Components
- **Known Forces:**
  - 200 lb acting downward on the x-axis.
  - 400 lb acting upward at point \( O \), perpendicular to the surface.
  - 300 lb acting upward along the y-axis.

- **Unknown Force:**
  - Force \( P \) and its line of action need to be found.

#### Diagram Explanation
- **Plane Dimensions:**
  - The plate is a rectangular surface with dimensions 4 ft by 3 ft.
  - Forces are acting at specific points across these dimensions.

- **Diagram Details:**
  - The force directions are indicated with arrows: 
    - A 200 lb force downward along the x-axis (left edge of the plate).
    - A 400 lb force upward at point \( O \).
    - A 300 lb force upward near the right edge along the y-axis, 2 ft from the edge.

#### Given Condition
The resultant force of this force-couple system is represented as a couple vector:
\[ C^R = -1100i + 1500j \, \text{lb.ft} \]

#### Objectives
1. **Analytical Solution:**
   - Solve the problem algebraically by hand to find the unknown force \( P \) and its point of action.
  
2. **Computational Solution:**
   - Write a computer code to solve for the force and verify the results of the analytical solution.

3. **Verification:**
   - Use the code to validate the hand calculations.

4. **Submission Requirements:**
   - Include both the code and its execution results showing the computed values for \( P \).

This exercise involves the understanding of statics principles, specifically involving the resolution of force systems and couple vectors. It also incorporates algebraic and computational approaches to problem-solving in engineering contexts.
