Someone can help me with this one please

**Analysis of Structural Mechanics Problem**

**Problem Statement:**
Rigid bar ABC is supported by a pin-connected bar (1). Bar (1) is 2.0 inches wide, 1.00 inch thick, and made of aluminum that has an elastic modulus of \( E = 12,000 \) ksi. Determine the maximum magnitude of load \( P \) that can be applied to the rigid bar without causing member (1) to buckle.

**Diagram Description:**
- The diagram features a rigid bar labeled ABC.
- Bar (1) is connected by pins at points B and D.
- The distance from C to B is 30 inches vertically.
- The horizontal distance from C to D is 56 inches in total (16 inches from C to the start of the inclined bar (1) at D, plus 40 inches along bar (1) from D to A).
- A downward force \( P \) is applied at point A.
- Bar (1) is shown at an angle supporting the structure at points B and D.

**Objective:**
Calculate the maximum load \( P \) that can be applied at point A without causing buckling in the aluminum bar (1) using Euler's buckling formula in mechanical engineering.
