I. Types of Forces & Deformations: Tension: Pulling force; elongation, necking (ductile), brittle fracture. Compression: Pushing force; shortening, bulging (ductile), splitting/shear (brittle), buckling (slender objects). Torsion: Twisting force; rotation. Shear: Opposing forces not on same line; inclined deformation. Bending: Force causing rotation; compression on one side, tension on the other; deflection. Bending moment M = F x L. Stiffness k = P/´. II. Stress & Strain: Stress (Ã): Force per unit area (Ã = F/A). Units: Pa, MPa. Strain (µ): Elongation per unit length (µ = L/L). Dimensionless. Hooke's Law: Ã = Eµ (linear elastic region). Young's Modulus (E): Material stiffness; slope of linear stress-strain curve. Units: MPa, GPa. III. Material Properties: Ductile: Large strain before failure (e.g., steel, aluminum). Brittle: Small strain before failure (e.g., concrete, chalk). IV. Construction Materials: Masonry: (Stone, brick, mortar) High compressive strength, low tensile strength. Timber: Moderate tensile and compressive strength, lightweight, anisotropic. Concrete: High compressive strength, low tensile strength; often reinforced with steel (RC). Steel: High tensile and compressive strength. Aluminum: Lightweight, ductile. Glass: Brittle. Composite: Materials combined for enhanced properties. V. Key Formulas: Stress (Ã) = Force (F) / Area (A) Strain (µ) = Change in Length (L) / Original Length (L) Hooke's Law: Stress (Ã) = Young's Modulus (E) * Strain (µ) Bending Moment (M) = Force (F) * Length (L) Made with nCreator - tiplanet.org
