Question
**Cantilevered Beam Deflection Analysis**

The cantilevered beam shown in the accompanying figure is used to support a load acting on a balcony. The deflection of the centerline of the beam is given by the following equation:

\[ y = \frac{-wx^2}{24EI} (x^2 - 4Lx + 6L^2) \]

Where:
- \( y \) = deflection at a given \( x \) location (meters)
- \( w \) = distributed load (Newtons per meter)
- \( E \) = modulus of elasticity (Newtons per square meter)
- \( I \) = second moment of area (meters to the fourth power)
- \( x \) = distance from the support (meters)
- \( L \) = length of the beam (meters)

**Illustration Description:**
The illustration accompanying the problem displays a cantilevered beam with a length \( L \) and a uniform distributed load \( w \) acting across its length. The beam is fixed at one end and free on the other, with the applied load directed downward. The distance \( x \) represents the position along the beam from the fixed support. The diagram helps visualize the problem setup for calculating deflections.

**Problem Statement (Problem 14.12):**
Using Excel, plot the deflection of a beam whose length is 5 meters with the modulus of elasticity \( E = 200 \) GPa and \( I = 99.1 \times 10^6 \) mm\(^4\). The beam is designed to carry a load of 10,000 N/m. Calculate and determine the maximum deflection of the beam.
