It's 3 m in length and made of copper (bond length = 2.57 e -10 m). The sides of the wire are 2mm wide. a) Calculate the number of chains in the wire. {{youtube>jsBxOSWTFyg?large}} ---- Part 2: b) Calculate the number of bonds per chain in the wire. {{youtube>D_gyawq_elI?large}} ---- Part 3: c) Calculate the macroscopic spring stiffness constant of the wire if the interatomic spring stiffness is 28 N/m. {{youtube>HYxWx85VcRk?large}} === Four Quadrants === {{183_notes:examples:youngs_nbonds_nchains_quadrant.png}} 183_notes/examples/videoswk4.txt Last modified: 2016/08/14 22:47by waterso8
