Load Test

Load a rod in a test machine. Read its curve, the energy it stores, and heat stress.

Physics · Class 11 · The stress–strain curve and stored energy · 7 simulations. For JEE, NEET and your boards.

What you'll learn

  1. Spring back or not: The elastic limit decides spring-back
  2. Energy in the wire: Stored energy is the area under F–ΔL
  3. Energy per cubic metre: Energy in each cubic metre: u = ½ Y ε²
  4. How thick is it?: Thicker wire, more energy
  5. Clamped rail: A clamped rod pushes on its clamps
  6. Cool it, then hang it: Cooling pulls a clamped wire tight
  7. Axes swapped: Axes swapped: the flatter line is stiffer
