One mole of tungsten (6.021023 atoms) has a mass of 184g, and its density is 19.3g/cm3, so the center-to-center distance between atoms is 2.511010m. You have a long, thin bar of tungsten, 2m long, with a square cross section, 0.14cm on a side. You hang the rod vertically and attach a 410kg mass to the bottom, and you observe that the bar becomes 1.49cm longer. From these measurements, it is possible to determine the stiffness of one interatomic bond in tungsten. Use g=9.8m/s2 throughout this problem. What is the spring stiffness of the entire wire, considered as a single macroscopic (large scale), very stiff spring? Answer in units of N/m. 006 (part 2 of 4 ) 10.0 points How many side-by-side atomic chains (long springs) are there in this wire? This is the same as the number of atoms on the bottom surface of the tungsten wire. Note that the cross-sectional area of one tungsten atom is 6.30011020m2. 007 (part 3 of 4 ) 10.0 points How many interatomic bonds are there in one atomic chain running the length of the wire? 008 (part 4 of 4) 10.0 points What is the stiffness of a single interatomic "spring"? Answer in units of N/m
