Examples of materials that are strong and weak.

📚 Quick Study Guide

• 💪 Strength: A material's ability to withstand an applied load without failure. High strength means it can handle more stress.
• 🧱 Types of Strength:
  • 💥 Tensile Strength: Resistance to being pulled apart.
  • 🔨 Compressive Strength: Resistance to being crushed.
  • ✂️ Shear Strength: Resistance to forces that cause layers to slide relative to each other.
• 🌱 Factors Affecting Strength: Molecular structure, bonding, and defects within the material.
• 🧪 Examples of Strong Materials: Steel, diamond, carbon fiber.
• 📉 Examples of Weak Materials: Chalk, some plastics, certain types of wood (when force is applied against the grain).
• 💡 Key Concept: Strength is not the only important material property; stiffness, toughness, and ductility also matter.
