The Concept Elasticity is a substance’s capacity to return to its original shape after being stretched or compressed. Think of a rubber band or a bow.
The Story In 1660, Robert Hooke discovered the law of elasticity, but the master archers and engineers of ancient India had been living by it for ages. They called it Sthitisthapaka—the property of “staying established”. They understood that a substance like the wood of a bow could store energy and return to its original shape. The Dhanurveda (Science of Archery) was actually a secret manual of material science, classifying which horns, woods, and sinews could hold the most “tension” without breaking. This practical knowledge of potential energy is what allows our modern bridges and buildings to “bend” without collapsing.

The Original Text
The Nyaya-Kandali (Verse 268) explicitly defines this elasticity in potential form.
Related Innovations The Dhanurveda tradition (about 5,000 BCE) classified materials based on how efficiently they could store potential energy. The Sharngadhara Paddhati (c. 1363 CE) described how to construct composite bows by layering horn, wood, and sinew to make them as flexible as possible.
Fun Fact Arjuna’s famous bow Gandiva was recognised for its high elasticity, allowing it to take a tremendous amount of tension without breaking.
The Modern Legacy Elasticity is vital in the construction of bridges, buildings, and automotive suspensions.
