Stress

Stress = F / A

Strain

Linear Strain = ΔL / L

Volume Strain = ΔV / V

Shearing Strain = θ = Δx / y

Hooke's Law and Moduli of Elasticity

Stress / Strain = E (Modulus of Elasticity)

Y = (F/A) / (ΔL/L) = FL / (AΔL)

Y = MgL / (πr²ΔL)

B = ΔP / (ΔV/V) = V(ΔP/ΔV)

Compressibility k = 1/B = (1/V)(ΔV/ΔP)
