Tec Thermal Expansion Cal

Thermal Expansion Calculator is an interactive Chrome extension for students, engineers, and anyone working with materials under temperature changes.

Enter basic material properties and instantly compute:
• Expansion length (ΔL = α · L · ΔT)
• Stress and reaction force if constrained
• Strain under temperature changes
• Overstress detection (failure check)

Key features:
• Supports both free and constrained expansion conditions
• Compare multiple materials side by side
• Visual bar charts to make results intuitive
• Lightweight and accessible directly from your browser toolbar

This extension combines accurate engineering formulas with a modern, responsive interface built on Next.js and shadcn/ui. It’s a fast, practical tool for classroom learning, quick engineering checks, or exploring how different materials behave when heated or cooled.
