What is residual strain?
Residual Strain is the same thing as permanent strain, as in permanent strain in a beam. If you refer to a stress vs strain plot, you'll see that this relationship in metals is linear up until the yield point where the metal plastically deforms. After stress slightly decreases due to this yielding, It will continue to increase, along with strain but on a more curve-shaped line. When stress is removed from the metal, it will slowly decrease back down to 0, but there will be an offset in the strain. The distance from where strain equals zero to this new point along the axis is the the residual strain left in the metal due to plastic deformation.
What is the definition of stress and strain as applied to a wire?
Type your answer stress; the force applied perunit surface area of the body that produce or tends to produce deformation in a body is called stress if a force F to a area A of a body then stress=force/area or o=f/a where o (stigma) denotes stress.obviously, the SI unit of stree is newton pper square meter(Nm-2). strain; the fractonal deformation resulting from astree is called strain
Definition of young modulus?
The young modulus young modulus(E) = stress/strain stress = force/area strain = extension(total length)/original length It is this property that determines how much a bar will sag under its own weight or under a loading when used as a beam within its limit of proportionality
How did the first Doctor Regenerate?
He died of old age, pretty much. He was an elderly man to begin with, and the stress and strain of defeating the Cybermen in 'The Tenth Planet' took its toll. He collapsed in the TARDIS and in a scene that no video footage remains for, he regenerates into the Second Doctor.
What is a pull a pull and a twist all examples of?
They are all mechanical stresses. Push is a compressive stress. Pull is a tensile stress and Twist is a type of shear stress.

Could you show the derivation of elastic strain energy per unit volume?
U= vol metric integral1/2(stress* strain)dxdydz
Can stress exists without strain and vice versa. eg a heated bar held rigidly at both ends has no strain but there is stress?
Wherever there is stress there is strain. In the example you noted, if heated bar expands freely without one end constained it changes its strain without stress; that strain is called eigenstrain. If the same bar is held rigidly then the eigenstrain resisted and you get stress and strain. So stress cannot exist without strain; but strain can exist without stress if it is eigenstrain.
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
Is the ratio of stress-strain in the region below the proportional limit on the stress-strain curve?
stress is directly proportional to strain up to the proportional limit. Their ratio is young's modulus.
How do you calibrate strain gauges?
The strain gage indicates strain, and the stress is from Hooke's law; stress = modulus times strain so you need to know the modulus of elasticity

What is Secant Modulus?
The secant modulus is the total stress or strain on an object as described by a stress-strain graph. The tangent modulus is the marginal strain.
Which comes first either stress or strain in an object?
When you have stress you also have strain - stress cannot exist without strain, so they come at the same time You can have strain without stress - like expanding something under temperature in a free state. If the state is not free, then you have stress occurring at the same time.
What is proof Stress for Steel?
proof stress can be found by referring to the stress/strain curve at the point where strain is = 0.2% original volume (the material has grown 0.2% in volume) proof stress will be given as a measurement of energy (MPa,KPa etc.) as it specifically refers to the amount of energy required to stress the material to 0.2% its original volume.
