Question Answer
Thin-Walled Sections: Angle Of Twist
Axial: Strain ε = σ/E = δ/L
Axial: Stress σ = P/A = Eε
Axial: Stiffness k = P/δ = P/(εL) = 1/f = EA/L
Axial: Flexibility f = δ/P = (εL)/P = 1/k = L/EA
Shear Modulus G = E/[2(1+ν)]
Axial: Shear Stress τ = V/Av = Gγ
Poisson's Ratio ν = -(ε'/ε)
Axial: Temperature Strain ε = α⋅ΔT
Axial: Temperature Displacement δ = εL
