Question
**Problem Description:**

The 22-lb link \( AB \) is pinned to a moving frame at \( A \) and held in a vertical position by means of a string \( B \) which can support a maximum tension of 10.0 lb. Determine the horizontal support reaction at pin \( A \) when the string is about to break. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point, and proper unit. Take \( g = 32.2 \, \text{ft/s}^2 \).

**Diagram Explanation:**

The diagram shows a mechanical setup involving:

- A vertical link \( AB \) that is 7 ft long, composed of two segments: 3 ft from \( A \) to a point halfway, and 4 ft from the halfway point to \( B \).
- The link is inclined by an angle since point \( C \) is horizontally 3 ft from \( B \).
- The link is supported by a string attached between points \( B \) and \( C \).
- Pin \( A \) connects the link \( AB \) to a horizontal structure.
- An acceleration \( a \) is indicated horizontally to the right.

**Answer Submission:**

Your Answer:
- [Answer box] [units box]

Ensure your answer includes the correct units and is rounded to two decimal places.
