What is elastic strain energy?
Potential Elastic Energy.
What is strain energy theory?
The strain theory is a state of deviation from bond angle of a normal tetrahedral angle.
What is the relation between elastic modulus and tensile modulus?
The elastic modulus, also called Young's modulus, is identical to the tensile modulus. It relates stress to strain when loaded in tension.
When a material is loaded within elastic limit the what is proportional to the what produced by the stress?
The displacement is proportional to the strain. This does not factor for creep and time.
What is the amount of stress applied to a material divided by the elastic strain caused by that stress called?
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 are examples of elastic spring force?
If you stretch a rubber band then release it, it will return to its original shape. That is by definition elastic strain. Anything that returns to its original shape after being affected by force underwent elastic strain. If it is permanently deformed (ie you bent a paperclip out of place and it wont return to its original shape) then it passes the elastic strain region and suffered plastic strain.
Is a rubber band a synonym for elastic strain?
yes.......................it is a stretchy elastic rubber band
What forms of energy are in stretched elastic?
strain energy when you let go of the elastic it is transferred as kinetic energy
How do you calculate the elastic limit?
By using stress-strain curve.
What is strain and stress?
stress is load per unit area; when an object is loaded it is under stress and strain and it stretches (strains) until it breaks at its ultimate strength. Stress i srelated to strain in the elastic region by Hooke's law: stress = elastic modulus times strain where modulus is a property of the material and strain is deflection over length
How are elastic strain energy are released during an earthquake?
elastic strain is released when the two plates are either slipping past each other or pulling apart or coming together
How do you know the material is elastic?
it depends on modulus of elasticity / young's modulus,,,,,,,which is ratio of stress and strain under elastic limit
What kind of force do your muscles exert on an elastic band when you stretch it?
Strain force
What is the property of visco elastic?
Viscoelasticity is the property of materials that are shown to be both viscous and elastic. Viscous materials are for example honey that resist shear flow and strain when stress is applied. Elastic materials strain but then quickly return to their original state. A viscoelastic material simply have elements of both.
How do you distinguish yield point and elastic limit?
On a stress strain curve the elastic limit is the point where the straight portion curve first starts to curve. When load is removed strain will return to zero. The yield point is a point on the curve just beyond the elastic limit. When load is removed strain will not return to zero. It will return approximately as a straight line parallel to the original, and have an offset strain value. The yield point offset is arbitrary but usually defined as 0.2% (.002 permanent strain) as most common strain devices can measure that amount.
What is plasticity in chemistry?
Plasticity is the characteristic of a metal where it undergoes inelastic strains beyond the elastic limit.Until the elastic limit point, the strain that a metal undergoes is elastic, meaning the metal will regain its original dimensions upon unloading. For example, during a tensile test, a metal pulled in tension to a strain below its elastic limit will return to its original dimensions upon release.However, if a metal is strained beyond the elastic limit into the plastic region, the strain will be inelastic, meaning the metal will be unable to return to its original dimensions upon unloading. Large deformations in ductile materials result in plastic flow.Metals experience periods of both elastic and plastic deformation. On a stress-strain curve, the elastic region is followed by the plastic region. Oftentimes, the elastic limit is approximated as equal to the proportional limit and (for mild steel) the yield stress.
A pole -vaulter first converts kinetic energy into?
