Across 1. A property of material by virtue of which it losses its elasticity. 3. Which dimenstion is incresed more to increase strength of a beam of coulomn. 5. The ratio of lateral strain to the logitudinal strain is called -------- ratio. 7. The materials which can be elastically stretched to large values of strain. 8. Which is more elastic-rubber or steel. 10. Among solid,liquid and gas,which possess the greater bulk modulus 13. The materials which have very small range of plastic extension. 14.
