**Beam Deflection Analysis under Linearly Increasing Load**

**Figures Description:**
The two figures illustrate a beam subjected to a linearly increasing distributed load and its resulting elastic curve (deflection). Figure (a) shows the beam with the load distribution increasing linearly from zero to \( w_0 \) along its length. Figure (b) depicts the deflected shape of the beam, where \( x = 0, y = 0 \) and \( x = L, y = 0 \).

**Problem Statement:**
A beam is subjected to a linearly increasing distributed load. The elastic curve (deflection) is depicted in the figure. The equation to find the maximum deflection (where \( \frac{dy}{dx} = 0 \)) is given below. The task is to create a MATLAB code to calculate this maximum deflection using the bisection method.

**Given Parameters:**
- \( L = 6.27 \, \text{m} \)
- \( E = 73000 \, \text{kN/cm}^2 \)
- \( I = 38000 \, \text{cm}^4 \)
- \( w_0 = 2.5 \, \text{kN/cm} \)

**Equations:**
The deflection equation is:
\[ y = \frac{w_0}{120EI} \left( -x^5 + 2L^2 x^3 - L^4 x \right) \]

The derivative of deflection (slope) is:
\[ \frac{dy}{dx} = \frac{w_0}{120EI} \left( -5x^4 + 6L^2 x^2 - L^4 \right) \]

**Task:**
Determine the value of \( x \) (location of maximum deflection) after 15 bisection iterations using initial guesses of 1 and 5.

**Choices (for \( x \)):**
- 2.5236
- 1.402
- 2.804
- 4.206

**Instructions:**
Write and execute a MATLAB code using the given parameters and equations to find which of the above choices corresponds to the value of \( x \) after 15 iterations of the bisection method.
