Question

 Using virtual work, determine displacement at B. (E = 29,000 ksi & I = 1,000 in^4)

### Problem Statement

**Objective:**  
Using virtual work, determine the displacement at point B in the beam.

**Diagram Description:**  
The diagram illustrates a simply supported beam with two supports, denoted as A and C. The beam is subjected to a uniformly distributed load of \(3 \, \text{k/ft}\) over a span of 25 feet (12.5 feet between A and B, and 12.5 feet between B and C).

**Dimensions and Parameters:**

- **Span Lengths:**
  - Between A and B: \(12.5 \, \text{ft}\)
  - Between B and C: \(12.5 \, \text{ft}\)

- **Load:**
  - Uniform distributed load: \(3 \, \text{k/ft}\)

**Material Properties:**

- Modulus of Elasticity (\(E\)): \(29,000 \, \text{ksi}\)
- Moment of Inertia (\(I\)): \(1000 \, \text{in}^4\)

### Analysis Method

- **Virtual Work:** Apply the principles of virtual work to calculate the displacement at point B.

This task requires an understanding of structural analysis and the application of energy methods to find deflections in beams.
