Calculate the change in length of the lead in an automatic pencil if you tap it straight into the pencil with a force of 6.8 N. The lead is 0.52 mm in diameter and 80 mm long. Round your answer to 5 decimal places. WebApr 28, 2015 · By analyzing phonon dispersion, we have evaluated the average Young’s modulus and Poisson’s ratio in graphite and in graphene grown on Ru(0001), Pt(111), Ir(111), Ni(111), and BC 3 /NbB 2 (0001). In both flat and corrugated graphene sheets and in graphite, we find a Poisson’s ratio of 0.19 and a Young’s modulus of 342 N/m.
