What is Histrasis? What is viscosity?

Question

Accepted Answer

Histrasis is the property of a material to resist change in shape or size under stress. Viscosity is the measure of a fluid's resistance to flow.

Histrasis is important in materials science and engineering as it determines the strength and durability of materials.
Viscosity is important in fluid mechanics and is measured in units such as poise or centipoise.
Examples of high viscosity fluids include honey and molasses, while low viscosity fluids include water and gasoline.
Viscosity can also be affected by temperature, pressure, and shear rate.
Histrasis and viscosity are both important properties to consider in the design of products and materials.
