Please clearly show all steps so your approach is easy to follow **Educational Module: Structural Analysis of a Three-Member Frame****Problem 2.2-14****Description:**The three-member frame structure depicted in Fig. P2.2-14 is subjected to a downward vertical load \( P \) at pin \( C \). The pins at \( B \), \( C \), and \( D \) apply axial loads to members \( BD \) and \( CD \), whose cross-sectional areas are \( A_1 = 0.5 \, \text{in}^2 \) and \( A_2 = 1.0 \, \text{in}^2 \), respectively. The problem consists of two parts:- (a) If the axial stress in member \( BD \) is \( \sigma_1 = 1200 \, \text{psi} \), what is the value of force \( P \)?- (b) What is the corresponding axial stress, \( \sigma_2 \), in member \( CD \)?**Diagram Explanation:**The accompanying diagram illustrates the frame and the relevant dimensions:- The frame consists of members connected at four joints labeled \( A \), \( B \), \( C \), and \( D \).- Member \( A \) is vertical, extending 18 inches down, split evenly between \( 9 \) inches intervals to points \( B \) and \( D \).- Member \( B \) to \( C \) is horizontal, measuring \( 24 \) inches (2 segments of \( 12 \) inches each) from \( A \) to \( C \).- Member \( D \) to \( C \) is inclined and subjected to the vertical load \( P \).- Relevant dimensions are given for structural analysis, with \( B \) and \( D \) serving as reference points.**Detailed Steps for Solution:**1. **Identify Crucial Parameters:** - Axial stress in member \( BD \): \( \sigma_1 = 1200 \, \text{psi} \). - Cross-sectional areas: \( A_1 = 0.5 \, \text{in}^2 \) for \( BD \), and \( A_2 = 1.0 \, \text{in}^2 \) for \( CD \).2. **Determine Force \( P \):** - Using stress-strain relationships and
