### Problem 2.3-4: Analysis of Strain in an Extensible Rod**Problem Statement:**A "rigid" beam BC of length \(L\) is supported by a fixed pin at \(C\) and by an extensible rod \(AB\), whose original length is also \(L\). When \(\theta = 45^\circ\), rod \(AB\) is horizontal and strain-free, that is, \(\epsilon(\theta = 45^\circ) = 0\). #### Objectives:(a) Determine an expression for \(\epsilon(\theta)\), the strain in rod \(AB\), as a function of the angle \(\theta\) shown in Fig. P2.3-4, valid for \(45^\circ \leq \theta \leq 90^\circ\).(b) Write a computer program and use it to plot the expression for \(\epsilon(\theta)\) for the range \(45^\circ \leq \theta \leq 90^\circ\).#### Explanation of Diagram:The diagram in Fig. P2.3-4 shows a beam-rod assembly where:- Point \(C\) is the fixed pin support.- Point \(A\) is where the extensible rod is fixed to a wall.- \(A\)B is the extensible rod of original length \(L\).- \(B\)C is the rigid beam also of length \(L\).- The angle \(\theta\) represents the rotation of beam \(BC\) from the horizontal axis.When the system is in a strain-free state, \(\theta = 45^\circ\).Understanding the setup and behavior of this mechanical system is crucial for applications related to mechanical engineering and material science, particularly in analyzing how structural components deform under various conditions.**Steps to Solve:**1. **Derive the Expression for \(\epsilon(\theta)\):** - Utilize geometric relationships and trigonometry to express the change in length of rod \(AB\) as a function of angle \(\theta\). - Consider both the initial (strain-free) state and the deformed states.2. **Develop a Computer Program:** - Implement the derived mathematical expression in a programming environment (e.g., Python, MATLAB). - Generate a plot of \(\epsilon(\theta)\) over the specified range of angles.This problem
