**Problem Statement:**

For the hoist shown below, when the weight \( W \) is 7,000 lb, the tension in AB is 13,000 lb.

**Question:**

Determine the shear stress in the 1-inch diameter pin at A which is in double shear: _____ lb/in².

Calculate your answer to 1 decimal place.

---

**Diagram Explanation:**

The provided diagram is a geometric representation of a hoist mechanism with a pinned joint. The diagram includes:

- **Points A, B, and C:** These are key points in the system where forces are applied or transferred.
- **AB Line:** Represents the cable or bar experiencing tension. The tension in AB is given as 13,000 lb.
- **Weight W:** Positioned at point C, with a value of 7,000 lb.
- **Measurements:** The distance from A to C is 7 feet, and from C to the vertical line passing through point B is 5 feet.

The pin at point A is subject to double shear due to the forces acting through it.

--- 

**Note:** To solve this problem, use the formula for shear stress and account for the double shear condition accordingly.
