Question: 

A scallop forces open its shell with an elastic material called abductin, whose Young’s modulus is about $2.0 \times 10^6 \textrm{ N/m}^2$. If this piece of abductin is 3.0 mm thick and has a cross-sectional area of $0.50 \textrm{ cm}^2$, how much potential energy does it store when compressed 1.0 mm?
