## Project Overview and Task
* **Task:** Design a welded steel L-shape bracket for workshop tool storage.
* **Key Constraints:** Must hold minimum 15 kg (target 25 kg), max 2 mm deflection, mild steel construction.
* **Dimensions:** 300 × 200 × 150 mm with M6 mounting holes.

## Design Evaluation
* **Concept Selection:** Three concepts were compared: Flat Plate, Gusseted, and Folded. 
* **Selected Design:** The Gusseted Bracket was chosen for its superior strength-to-fabrication balance.

## Technical Development
* **CAD & Drawings:** Created fully dimensioned technical drawings (Material: Steel A36, THK 12mm).
* **Engineering Calculations:** 
  * **Load Capacity:** Stress analysis confirms suitability for mild steel limits.
  * **Safety Margin:** Target capacity of 25 kg achieved through gusset reinforcement.
  * **Deflection:** Check confirms deflection remains under the 2 mm limit.

## Project Management and Quality
* **Schedule:** 6-week delivery following a formal session log.
* **Specification Compliance:** 10/10 requirements met, including safety, material, and structural integrity.
* **Risk Management:** Mitigated issues related to CAD misalignment, weld distortion, and hole positioning accuracy.

## Conclusion
* Final documentation is workshop-ready. Key successes included strong planning and effective use of a decision matrix for design selection.
