Purple background sheet with title Strength of Materials at top. Sections on deformations show diagrams of axial tension with arrow pulling cylinder ends labeled σ tension compression with inward arrows on cylinder bending with curved beam under load labeled σ bending torsion with twisted cylinder labeled τ torsion shear with sliding blocks labeled τ shear. Twin walled cylinder diagram with inner and outer walls labeled. Bolt connection analysis shows bolt under load with stress formula σ = F/A. Formulas for modulus of elasticity E = σ/ε poissons ratio ν = -ε_lat/ε_axial bulk modulus K = -P/(ΔV/V) shear modulus G = τ/γ. Thermal stress section with formula σ_th = α E ΔT and diagram of heated bar. Power transmission with gears. Principal stresses and von mises stress formulas with mathematical expressions. Torsion in thin walled tubes diagram.
