Pro Tips for Choosing Your Topic

• Always start with a 'Failure Mode'—analytical engineering essays are strongest when they examine why something broke or underperformed.
• Quantify your arguments; use specific constants, material properties (like Young's Modulus), or efficiency percentages to ground your analysis.
• Check the 'Normalization of Deviance'—many engineering disasters are caused by culture, not just physics. Use this framework for ethics papers.
• Utilize the IEEE or ASME citation styles early to ensure your technical references are formatted according to professional standards.
• Narrow your scope to a specific component (e.g., 'O-rings' rather than 'The Space Shuttle') to allow for deep technical drill-down.
