**Problem Statement:** 

Determine the magnitude of the pin force at A.

Given parameters:
- Weight (W) = 795 lb
- Distance a = 3.6 ft
- Distance b = 2.7 ft
- Radius (r) = 9 in.

**Diagram Explanation:**

The diagram depicts a mechanical system involving a weight (W) hanging from a pulley at point C. The pulley has a radius (r). The system consists of several points: C, B, A, and D, connected by rigid members. Point B and D are connected by a slanted bar, and D is attached to a vertical wall. The horizontal bar runs from point C to the point on the wall where it is connected at B. The bar is split into three sections:
- Distance between C and A is denoted by 'a'
- Distance between A and B is also denoted by 'a'
- Vertical distance between B and D is denoted by 'b'

**Objective:** 

Calculate the force at point A using the provided parameters.

**Solution Input Box:** 

An input box is provided for students to input their answer in pounds (lb).

---

Answer: \( A = \_\_\_\_ \text{lb} \)

---

This problem involves understanding equilibrium conditions and mechanical forces within the system.
