What is the amount of stress applied to a material divided by the elastic strain caused by that stress called?
Nated14
This is known as the Modulus of Elastisity, or Youngs Modulus (in tension/compression) and will be a constant as long as the deformation is in the elastic range.

What is elastic modulus?
In a tensile test, a specimen of material is pulled apart slowly until it breaks. Measurement is continuously taken of the increase in length and the force applied. The increase in length is normalized by dividing it by the original length, and the force is converted to stress by dividing it by the original cross-section area of the specimen. The results are plotted on a graph, called a stress-strain curve, with the stress on the Y axis and the strain on the X axis. The initial part of the curve is usually linear. That linear section is called the elastic region. The slope of the line in that area, which is stress divided by strain in the elastic region, is the elastic modulus.
What is definition of britleness for testing material?
A material will be graded as brittle when it breaks with only a small amount of strain. Its brittleness is based on the amount of deformation used to break the material.
What is shear modulus depends on?
Shear modulus, which is also often referred to as the modulus of rigidity or torsion modulus, is a measure of the rigid or stiff nature of different types of solid materials. It is derived from the material's ratio of its shear stress value to that of shear strain. Shear stress is a value of how much force is applied to a square area of a material, usually measured in pressure values of pascals. Strain is the amount that the material has deformed under stress divided by its original length. The shear modulus value is always a positive number and is expressed as an amount of force per unit area, which is generally recorded as metric gigapascals (GPa) because the values are more practical than English equivalents.
How is hooke's law releted to torque wrench action?
Torque wrenches depend on a modern generalisation of Hooke's Law. The deformation of an elastic material (even the steel out of which parts of a torque wrench are made) is proportional to the stress to which it is subjected. When you use a torque wrench part of it follows the thing your turning and part of it does not. That part of the torque wrench twists slightly; it's being deformed and obeys Hooke's Law. The more twist, the more torque is being applied. The needle amplifies the amount of twist so that you can read the torque on the gauge.
What is the amount of axial stress on a member which is subjected to a sudden load when compared to load applied gradually?
The maximum stress induced in a body due to suddenly applied load is twice the stress induced when the same load is applied gradually
What makes material stretchy?
Materials (i assume you mean clothes of fabrics) are stretchy due to the amount of elastic in the fabric. More elastic means stretchier fabric, less elastic means it will not be as stretchy.

What is elastic limit and hooke's law?
The Law of elasticity states that the strain (deformation) of an elastic object is proportional to the stress applied to it. Since stresses and strains have multiple independent components, the 'proportionality factor' is represented by a linear map (a tensor) constituting a matrix of real numbers.
What factors control wheather a rock behaves as a brittle material or a ductile material?
The amount and rate of stress applied, the type of rock, and the temperature and pressure under which the rock is strained.
What is the difference between stiffness and toughness?
Both the properities are having the ability to absorb the energy,but they differ in elastic properity,If the same amount of energy being absorbed by the materials having mechanical properity of toughness and stiffness,The elastic range of tough material is more ,than the stiff material when compared.Spring material is tough,but Low carbon mild steel with annealed heat treatment if stiff,Hence the difference can be made between them,
How the resistance of the material is determine?
Resistance is measured in ohms and the amount of resistance that allows one ampere of current to flow when one volt is applied is one ohm.
The amount of material in a substance?
The amount of material in a substance is mass.
What amount of material contained by a body?
This amount of material is the mass.
Amount of material contained by a body?
This amount of material is the mass.
Describe how the resistance of a material is determined?
Resistance is measured in ohms and the amount of resistance that allows one ampere of current to flow when one volt is applied is one ohm.
Does The Law of Applied Force state that a body's change in mass is proportional to the amount of force applied to it?
The Law of Applied Force states that a body's change in mass is proportional to the amount of force applied to it.
Does the law of applied forced state that a body's change in mass is proportional to the amount of force applied to it?
The Law of Applied Force states that a body's change in mass is proportional to the amount of force applied to it.
