### Beam Deflection Analysis

The cantilever beam consists of a rectangular structural steel tube shape \([E = 27000 \, \text{ksi}; \, I = 450 \, \text{in}^4]\). For the loading shown, determine:

1. **The beam deflection \(v_B\) at point B.**
2. **The beam deflection \(v_C\) at point C.**

Assume the following parameters:
- \(P = 10.9 \, \text{kips}\)
- \(w = 2.9 \, \text{kips/ft}\)
- \(L_{AB} = 7.6 \, \text{ft}\)
- \(L_{BC} = 4.6 \, \text{ft}\)

#### Diagram Explanation
A cantilever beam is illustrated, fixed at one end (point A) and extending horizontally to the right. The beam is subjected to two different types of loads:
- A uniformly distributed load \(w\) over the segment \(L_{AB}\).
- A concentrated load \(P\) at the end of the beam (point C).

The length \(L_{AB}\) is the distance from point A to point B, and \(L_{BC}\) is the distance from point B to point C. These segments are denoted on the diagram as follows:
- \(L_{AB} = 7.6 \, \text{ft}\)
- \(L_{BC} = 4.6 \, \text{ft}\)

#### Graph Explanation
The diagram illustrates the following:
- A vertical arrow pointing downward labeled \(P\) at the end of the beam (point C), indicating the concentrated load.
- A series of smaller vertical arrows evenly distributed along the length of \(L_{AB}\), indicating the uniformly distributed load \(w\).

### Results
The deflection values at points B and C are calculated as follows:
- **(a) \( v_B = -0.6016 \, \text{in.} \)**
- **(b) \( v_C = -1.2143 \, \text{in.} \)**
