Can a liquid resist shear stress?
Yes, a liquid can resist shear stress up to a certain extent, which is determined by its viscosity. Viscosity is a measure of a liquid's resistance to flow and deformation; higher viscosity means greater resistance to shear stress. However, unlike solids, liquids do not have a definitive shape and will eventually flow when subjected to sufficient shear stress. Therefore, while they can resist shear stress temporarily, they cannot maintain that resistance indefinitely.
Why liquid is fluid?
A fluid is a substance, such as a liquid or gas, that can flow, has no fixed shape, and offers little resistance to an external stress.
What does viscosity mean for a liquid?
It is the ability of the liquid to flow. The higher the viscosity, the less the ability to flow. For example, oil is more viscous than water; honey is more viscous than oil.
The resistance of a liquid to following is its?
the resistance of liquid to following is its viscosity.
Liquids resistance flow is measured how?
Liquid resistance to flow, often referred to as viscosity, is typically measured using a viscometer. Viscosity can be assessed through various methods, such as capillary, rotational, or falling ball viscometry, depending on the fluid's characteristics. The measurements indicate how easily a liquid flows under applied stress, with higher viscosity indicating greater resistance to flow.
What is the difference between yield stress and proof stress?
yield stress is the maximum resistance to deformation per unit area and proof stress is the allowable resistance to deformation per unit area.
Do liquid and gases have high dynamic viscosity?
No, liquids and gases typically have lower dynamic viscosity compared to solids. Dynamic viscosity is a measure of a fluid's resistance to deformation under shear stress, and both liquids and gases have lower resistance compared to solids due to their molecular structure and higher mobility of particles.
What is stress tolerance?
Measure of resistance to force.
What hormone increases resistance to stress?
epinephrine
What type of resistance stress applied in a longitudinal direction is provided best by?
Tensile stress provides the best resistance when applied in a longitudinal direction. This type of stress occurs when forces are applied to stretch an object, causing it to pull apart. Materials like steel and Kevlar are known for their high resistance to tensile stress.
The resistance of a liquid flowing is its?
solid
What is resistance of a liquid flowing?
viscosity
