A force stretches a wire by $1.0 \mathrm{mm}$. a. A second wire of the same material has the same cross section and twice the length. How far will it be stretched by the same force? b. A third wire of the same material has the same length and twice the diameter as the first. How far will it be stretched by the same force?

Key Concepts

Elasticity

Elasticity is the property of a material that enables it to return to its original shape after being deformed by an applied force. It governs how materials stretch under tension and compress under pressure, with the deformation remaining proportional to the applied load as long as the material is within its elastic limits.

Young's Modulus

Young's modulus is a specific measure of a material's stiffness and is defined as the ratio of tensile stress to tensile strain. This constant allows for the quantification and comparison of how much a material will extend under a given force, and is fundamental for calculations involving the deformation of materials.

Hooke's Law

Hooke's Law states that, within the elastic limit of a material, the extension or compression produced by an applied force is directly proportional to the magnitude of that force. This principle is the cornerstone for understanding and calculating small deformations in materials under tensile or compressive stress.

Effect of Geometric Factors on Elastic Deformation

The extent to which a material deforms under a given force is influenced by its geometry, notably its length and cross-sectional area. Specifically, a longer material tends to extend more under an applied force, while a larger cross-sectional area results in a smaller extension due to the distribution of force over a greater area.
