← A copper wire and a steel wire have the same length and the same thickness. Each holds the same load. How many times the steel wire's stretch is the copper wire's stretch? (Y: steel 2.0 × 10¹¹ Pa, copper 1.1 × 10¹¹ Pa.)A copper wire is stretched so that its length grows by 2.0 × 10⁻³ of itself. Poisson's ratio for copper is 0.34. By what fraction of itself does its diameter shrink? →
