Young's Modulus Compared
Four wires (steel, copper, Al, brass) under same load — stiff materials stretch less.

Bulk Modulus
B = −ΔP/(ΔV/V) — cube compresses under hydrostatic pressure. 3D iso visual + live bar.

Shear Modulus
G = F/(Aφ) — block sheared into a parallelogram. Watch angle φ grow linearly with τ.

Poisson's Ratio
ν = −ε_T/ε_L — rod extends axially, contracts laterally. See the grid deform.

Elastic Potential Energy
U = ½σε·V — area under σ–ε curve fills as the wire stretches; energy bar grows live.
