**Problem 5-16:**

Determine the tension in the cable and the horizontal and vertical components of reaction of the pin at \( A \). The pulley at \( D \) is frictionless and the cylinder weighs 80 lb.

**Diagram Explanation:**

The diagram consists of a horizontal beam pinned at point \( A \), extending to point \( C \), where it supports a hanging cylinder weighing 80 lb. The beam is supported by a cable that runs from point \( B \) over a frictionless pulley at point \( D \), connecting back to point \( C \).

- **Beam \( ABC \):**
  - \( AB \) is a horizontal section 5 ft in length.
  - \( BC \) is another horizontal section 8 ft in length (5 ft + 3 ft).

- **Pulley at \( D \):**
  - Positioned vertically above \( B \), supporting the cable.
  
- **Cable:**
  - Runs from \( B \) to \( D \) to \( C \).

- **Forces:**
  - The weight of the cylinder creates a downward force of 80 lb at point \( C \).
  - The reaction at pin \( A \) has horizontal and vertical components to be determined.

**Objective:**

- Determine the tension in the cable.
- Calculate the reaction components at pin \( A \).
