Question 5.
Calculate the increase in elasticity for a carbon nanotube subjected to a tensile force, given that its Young's modulus is significantly higher than that of steel.
Show hintHide hint
Research on Young's modulus values for specific materials.
Question 6.
Discuss the impact of introducing defects into a nanomaterial's structure and how this would alter its elastic properties, supporting your discussion with theoretical principles.
Show hintHide hint
Consider how imperfections in structures affect the overall strength and resilience.
