**Problem 3**
A horizontal column is rigidly attached to two vertical bars as shown. Find the expression for \( P_{cr} \) for buckling in the plane using the general solution to buckling of elastically restrained columns.
**Diagram Explanation:**
The diagram illustrates a horizontal column \( BE \) with two rigid connections at points \( B \) and \( E \) to vertical bars \( AC \) and \( DF \) respectively. The bars have a length labeled \( L \) and a flexural rigidity denoted as \( EI \).
- **Point \( A \)** and **Point \( F \)** are fixed supports at the base of each vertical bar.
- **Point \( C \)** and **Point \( D \)** are the top ends of the vertical bars, connected to a lateral support.
- A horizontal force \( P \) is applied at points \( B \) and \( E \) in opposite directions, indicating potential buckling forces.
**Problem 4**
*The contents for Problem 4 are not visible in the image.*

This setup requires finding the critical load (\( P_{cr} \)) for the column when subject to buckling, using the properties of the supports and the connections specified in the diagram.
