Pressure Vessels

The term pressure vessel refers to a closed container that contains gas or liquid at a different pressure than environment pressure. The pressure vessels have a wide scale of applications in our day-to-day lives and other industrial places. Some common examples of pressure vessels are gas cylinders, autoclaves, compressor vessels, etc.

### Structural Analysis: Solid Bars AC and BD

#### Overview:
The structure shown consists of two solid bars, AC and BD, and supports a vertical load, \( P = 300 \) lbs, applied at point A. The bars are connected using 3/8-inch diameter pins.

#### Diagram Descriptions:
1. **Front View**:
- Bars AC and BD are depicted.
- Bar AC extends horizontally, with point A being on the left and point C on the right.
- The vertical load \( P = 300 \) lbs is applied downwards at point A.
- Bar BD is depicted as a vertical bar, with D at the top and B at the bottom.
- The horizontal distance between point B and point D is \( 3/4 \) inches, and the vertical distance is \( 6 \) inches.
- Points B and C are connected, making an intersection where bars AC and BD align perpendicularly.

2. **Side View**:
- Displays the thickness of bars and the connections.
- Shows that bars BD and parts of AC are 1/4 inch thick.
- Panel D and B are represented with their connecting pins clearly seen in a side perspective.

3. **Top View**:
- Highlights bars AC and BD from an overhead angle.
- Clearly shows the distances from point A to point B (7 inches) and point B to point C (5 inches).

#### Key Dimensions:
- Vertical Load \( P \) at point A: \( 300 \) lbs.
- Distance from A to B: \( 7 \) inches.
- Distance from B to C: \( 5 \) inches.
- Vertical distance between D and B: \( 6 \) inches.
- Horizontal distance between B and D: \( 3/4 \) inches.
- Thickness of bars: \( 1/4 \) inch.
- Diameter of pins: \( 3/8 \) inch.

This setup creates a clear understanding of the structural mechanics of bars AC and BD, as well as the load distribution at the connections facilitated by the 3/8-inch diameter pins.

For more details or to delve deeper into structural analysis involving forces, moments, or stresses in the bars, additional calculations based on principles of mechanics and material strengths would be necessary.
