1. Illustrate the stress and strain of solids.
2. What do you mean by the Young’s modulus for steel is ð’€ = ðŸ. 🎠× ðŸðŸŽðŸðŸ ð‘µð’Žâˆ’ðŸ ? Explain briefly.
3. Gold has a face centered cubic unit cell and has the density ðŸðŸ—. 👠𒈠ð’„ð’Žâˆ’👠. Calculate the length along an edge. (ð´ð‘¢ = 197 ð‘” ð‘šð‘œð‘™ −1 )
4. Write down five real life applications of surface tension.
5. A capillary tube with an inside diameter of ðŸ“ðŸ’🎠ðð’Ž can support a ðŸðŸŽðŸŽ ð’Žð’Ž column of liquid that has a density of ðŸðŸ‘ðŸ“ðŸŽðŸŽ ð’Œð’ˆð’Žâˆ’👠. If ð’‰ = ðŸŽ. ðŸ then is it possible to find the surface tension of the liquid? If not, then write down the reason.
6. Write a short note on polymer materials and amorphous solid.Â
