Graphite young's modulus
WebThe lead is 0.52 mm in diameter and 58 mm long. The “lead” in pencils is a graphite composition with a Young’s modulus of about 1 • 109 N/m2. 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 3.6 N. The lead is 0.52 mm in diameter and 58 mm long.
