(7%) Problem 14: The "lead" in pencils is a graphite composition with a Young's modulus of about 1 . 109 N/m2. Shah, Isha - shahis 17 @students.rowan.edu Calculate how much shorter (in mm) the length of the lead becomes in an automatic pencil if you tap it straight into the pencil with a force of 3.8 N. The lead is 0.46 mm in diameter and 58 mm long.
