What else can I help you with?
Is the shear modulus of steel greater than air?
yes
What is shearing in graphics?
i dont knowany body know tel about shear in computer graphics very urgent
What are the different types of slope failure for rock slopes?
1. shear failure 2. rock flow 3. rock fall
Why are splines are better than keys?
Splines are stronger than the shear strength of a key. More than one key would be stronger than one. eD
When calibrating a 70 degree shear wave U.T probe using an A4 block where should the indications appear on the U.T screen would it be the same as using a 45 degree 25 and 100 mm?
Yes. Ravi Singh E-mail: pioneerinsp@yahoo.com
What is the definition of angle of shear?
The angle of shear is the angle between the shear plane and the direction perpendicular to the normal stress in a material under shear stress. It represents the amount of deformation occurring due to shear forces acting on the material.
What is the relationship between resolved shear stress and critical resolved shear stress in materials science?
In materials science, the relationship between resolved shear stress and critical resolved shear stress is that the critical resolved shear stress is the minimum amount of shear stress needed to cause dislocation movement in a material. Resolved shear stress is the component of an applied stress that acts in the direction of dislocation movement. When the resolved shear stress exceeds the critical resolved shear stress, dislocations can move and deformation occurs in the material.
What is the relationship between shear stress and shear rate in fluid mechanics?
In fluid mechanics, shear stress is the force per unit area applied parallel to the surface of a fluid, while shear rate is the rate at which adjacent layers of fluid move past each other. The relationship between shear stress and shear rate is described by Newton's law of viscosity, which states that shear stress is directly proportional to shear rate. This means that as the shear rate increases, the shear stress also increases proportionally.
What is the relationship between normal stress and shear stress in a material under mechanical loading?
Normal stress and shear stress are two types of stresses that act on a material under mechanical loading. Normal stress is a force applied perpendicular to the surface of the material, while shear stress is a force applied parallel to the surface. The relationship between normal stress and shear stress depends on the material's properties and the direction of the applied forces. In general, normal stress and shear stress can interact and affect each other, leading to complex mechanical behaviors in the material.
Definition of hooke's law in shear?
Hooke's Law in shear states that the shear stress in a material is directly proportional to the shear strain applied, as long as the material remains within its elastic limit. This relationship is expressed mathematically as τ = Gγ, where τ is the shear stress, G is the shear modulus, and γ is the shear strain.
What is the relationship of shear angle and rake angle?
∅=45°+ α- β∅=shear angleα= rake angleβ= friction angle
What are some examples of Newtonian fluids and how do they behave under shear stress?
Newtonian fluids are fluids that have a constant viscosity, such as water and most oils. When subjected to shear stress, Newtonian fluids exhibit a linear relationship between the shear rate and shear stress, meaning they flow consistently and predictably.
What is the relationship between shear stress and velocity gradient in a Newtonian fluid?
In a Newtonian fluid, shear stress is directly proportional to the velocity gradient. This relationship is described by Newton's law of viscosity, which states that the shear stress (τ) is equal to the viscosity (μ) of the fluid multiplied by the velocity gradient (du/dy). Mathematically, this relationship can be represented as τ = μ*(du/dy).
What is the relationship between basic friction angle and residual friction angle of sandstone?
For rock, the basic friction angle is somewhat less than residual angle. The basic friction strength is that shear resiatance of two smooth surfaces. The residual shear atrength is that for two rough surfaces after long shearing. At residual state, the shear resistance almost keeps constant and no shear-dilation.
What is the relationship between the shear modulus, Poisson's ratio, and the shear modulus equation in materials science?
In materials science, the shear modulus, Poisson's ratio, and the shear modulus equation are related. The shear modulus represents a material's resistance to deformation under shear stress, while Poisson's ratio describes how a material deforms in response to stress. The shear modulus equation relates these two properties mathematically, helping to understand a material's behavior under shear stress.
What is the schmid factor?
The Schmid factor m is part of the equation for the critical resolved shear stress τ0. The critical resolved shear stress is the component of shear stress in a slip plane, resolved in the direction of slip, necessary to initiate slip in a grain (plastic deformation in metals). m = cos(κ)cos(λ) ; τ0 = mσ κ - the angle between the applied load direction and the slip plane normal. λ - the angle between the applied load direction and the slip direction. σ - the applied stress or load
What is the relationship between the shear g and the shear rate?
Viscosity is constant to the flow of the fluid.
