1. The problem statement, all variables and given/known data A wire of diameter 0.2mm stretches by 0.20% when a 6.28-N force is applied. What is the elastic modulus of the wire? 2. Relevant equations Elastic Modulus=F/A/L/[tex]\Delta[/tex]L 3. The attempt at a solution r=.1mm=1x10-4m 6.28N/(2[tex]\pi[/tex]1x10-8/.02=5x109N/m2 The right answer is 1.0x1011. What am I doing wrong?
