I need to replace the elastic in my hiking pants because it has stretched out.

She chose elastic wristbands for the workout because they allow free movement.

The fabric stretched elastically over the frame, returning to its original shape when released.

The researcher measured the elastances of various polymer samples to determine their stiffness.

During the materials test, the researcher measured the elastication of the polymer to determine how it would respond under repeated stretching.

During the fatigue test, the research team documented multiple elastications that altered the material's stiffness.

To compute the semi-elasticity of the consumption function at income level x, economists take the derivative f'(x) to measure the absolute change in consumption resulting from a one-unit increase in income.

The modulus of elasticity of the composite material increased after heat treatment, improving its load-bearing performance.

The engineering report compared the moduli of elasticity of aluminum, steel, and titanium to determine the best material for the prototype.

To estimate the point elasticity of the demand curve, we differentiate the demand function and evaluate the derivative at the chosen price.
