Question

The strain energy of a wire depends on all the following EXCEPT ______.

Options

• Young's modulus of the material

• Cross-sectional area of the wire

• Color of the wire

• Volume of the material

Answer 1

The strain energy of a wire depends on all the following EXCEPT the colour of the wire.

Explanation:

Strain energy depends on material properties (Young's modulus), geometry (area and length), and extension. The colour of the wire is a physical property that does not affect its mechanical behaviour or strain energy.
