Construction
Structural mechanics
Stress, strain, reactions and bending moments.
Construction
Section stress
σ = F / A→ConstructionLinear strain
ε = Δl / l→ConstructionStress using Hooke's law
σ = Eε→ConstructionSupport reaction under central load
R = P / 2→ConstructionMaximum beam moment
Mₘₐₓ = qL² / 8→ConstructionElastic modulus from stress
E = σ/ε→ConstructionLinear load from total load
q = P/L→ConstructionSupport reaction from uniform load
R = qL/2→
