Stress-Strain Lab
Pick a material and pull. The strain slider walks the specimen along its engineering stress-strain curve — Hookean elastic, then yield, strain-hardening up to the ultimate strength, then necking and fracture — with Young's modulus, yield strength and UTS marked. Watch where each material gives, how ductile it is, and how brittle cast iron snaps with almost no warning.
