**Problem 7.35**

Use the virtual work method to determine the slope and deflection at point D of the beam shown.

---

**Diagram Explanation:**

- **Beam Layout:**
  - The beam spans a total of 32 feet, divided into three sections: 
    - \(AB = 16 \text{ ft}\)
    - \(BC = 8 \text{ ft}\)
    - \(CD = 8 \text{ ft}\)

- **Loads:**
  - A uniformly distributed load (UDL) of \(2.5 \text{ k/ft}\) acts over the section \(AB\).
  - A point load of \(35 \text{ k}\) is applied at point \(D\).

- **Support and Connections:**
  - There is a hinge connection at point \(C\).

- **Material Properties:**
  - The moment of inertia \(I\) is \(4,000 \text{ in}^4\) from \(A\) to \(B\) and \(3,000 \text{ in}^4\) from \(B\) to \(D\).
  - The modulus of elasticity \(E\) is constant at \(30,000 \text{ ksi}\).

The task is to calculate the slope and deflection at point \(D\) using the virtual work method with these variables.
