Modern engineers have tested these principles. In 2015, a team in Gujarat reconstructed a small-scale model based on the text’s gear ratios and found the mechanism to be physically plausible, using water wheels or animal power for rotation.

The text covers the entire spectrum of construction across 83 chapters:

The text discusses the constituent elements, features, and construction details of these yantras, indicating a deep understanding of mechanics. 3. The Mythical Dharu Vimanas (Flying Machines)
