Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the primary engineering function?Mitigates stress concentration, thereby increasing fatigue life and preventing fracture
2. What is the application domain?Crucial in welded joints, mechanical components, and structures across all engineering fields
3. What is a fillet in mechanical engineering?A fillet is a rounded corner that smooths the meeting of two surfaces or edges. It replaces a sharp angle with a gentle curve.
4. Why do engineers use fillets instead of sharp corners?Sharp corners gather stress and can break. Fillets spread the force over a larger area, helping parts last longer.

Stress Concentration: The localized increase in stress around geometric discontinuities like sharp corners.
Fatigue Life: The number of stress cycles a material can withstand before failure.
Computer-Aided Design (CAD): Software used by engineers to create, modify, analyze, and optimize designs.
