Poiseuille's law is used to calculate the viscosity of a fluid in a pipe.

Poiseuille's law describes the flow of a viscous fluid through a capillary tube and relates viscosity to flow rate.

Charles's Law states that the volume of a gas is directly proportional to its absolute temperature at constant pressure.

The elastic limit is the maximum stress that a material can withstand without undergoing permanent deformation.

The shear modulus is defined as the ratio of shear stress to shear strain in a material.

Poisson's ratio (ν) is defined as the ratio of lateral strain to longitudinal strain.

Gases have no definite shape or volume and will expand to fill the entire volume of their container.

Viscosity is a measure of a fluid's resistance to flow.

Dynamic viscosity can be calculated using Poiseuille's law.

In a Newtonian fluid, shear stress (τ) is directly proportional to the shear rate (du/dy) with the proportionality constant being the dynamic viscosity (μ).

Density does not directly affect surface tension; it is influenced by temperature, impurities, and the nature of the liquid.

The buoyant force depends on the density of the fluid, the volume of the object submerged, and the acceleration due to gravity, but not on the depth of the object.

The buoyant force depends on the volume of fluid displaced, the density of the fluid, and the acceleration due to gravity, but not on the shape of the object.

While temperature, pressure, and composition affect fluid density, volume does not directly affect density.

While temperature, impurities, and the nature of the liquid affect surface tension, density does not directly influence it.

Flow rate does not affect the viscosity of a fluid; viscosity is a property of the fluid itself.

Honey has a higher viscosity compared to water, air, and olive oil due to its thicker consistency.

Honey has a much higher viscosity compared to water, air, and gasoline.

A Newtonian fluid has a constant viscosity regardless of the shear rate applied.

Non-Newtonian fluids exhibit a change in viscosity with varying shear rates, unlike Newtonian fluids which have a constant viscosity.

An ideal fluid is defined as incompressible and having no viscosity.

Gases are highly compressible, meaning their volume can change significantly under pressure.

Cornstarch in water exhibits non-Newtonian behavior, as its viscosity changes with the applied shear stress.

A Newtonian fluid has a constant viscosity regardless of the shear rate.

Fluids are often considered incompressible for practical purposes, especially in hydrodynamics.

Cornstarch in water (oobleck) is a non-Newtonian fluid that exhibits varying viscosity depending on the shear rate.

Plastic deformation is not elastic; it is permanent deformation that occurs beyond the elastic limit.

Tensile modulus is not a standard term; the correct terms are Young's modulus, shear modulus, and bulk modulus.

Thermal stress is a result of temperature changes, while tensile, compressive, and shear stresses are types of mechanical stress.

The elastic potential energy stored in a stretched wire is given by U = (1/2) * Y * (ΔL^2 / L), which is proportional to the square of the elongation.
