Answer to Question #291284 in Molecular Physics | Thermodynamics for Vishnu

Question

Determine the strain tensor of a long rod of length / hanging vertically from the celling in a gravitational field of strength g.

Answer 1

Solution;

Let E be the Young's modulus of the rod,A be the cross-sectional area and L be the length.

The strain is;

$\frac{\Delta L}{L}=\frac{mg}{AE}$
