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

∙ 13y agostress is the ratio of internal restoring force to the area of cross section of the wire .in general internal restoring force is equal to the applied force . stress=force applied/ area of cross section.
and strain is the ratio of change in dimension to the original dimension. therefore
strain = change in dimension / original dimension.

How can electric currents and magnets exert force on each other?
Electric currents and magnetic fields are by nature and by definition related to each other. In general, a magnetic field is created by the rotation of charge. If you imagine an electron following a circular path, a magnetic field would be created in the direction perpendicular to the plane of the circle.On the other hand, electric current is defined as the flow of charge. So, an electron flowing along a wire results in current flow. This also means that the electron following a circular path (as above) creates an electric current along that same path.If a circular flow of current results in a magnetic field perpendicular to the circle, what happens for current flow along a straight wire? Basically, we see a magnetic field which bends around the wire. Imagine exactly the reverse as before, with the magnetic field circling around the direction of current flow.This basic relationship between electric current and magnetic fields results in some interesting interactions:1. Many electromagnets work by the following principle: A coil of wire is made so that when voltage is applied the current will follow a circular path. As discussed above this circular movement of charge results in a magnetic field. In this case, you can imagine the direction of the magnetic field as the line through the center of the wire coil.2. The Hall Effect: When current is applied across a conductive slab and a magnetic field is applied perpendicular to current flow, a voltage is generated in the third perpendicular direction. This occurs due to the interaction of the magnetic field generated by the flow of current and the applied magnetic field.
How to wire a 5 wire thermostat properly without a diagram?
depends on whether thermo used on gas or elec. unit, heat pump, strip heat, etc. red wire is hot wire. White wire goes to heat. yellow wire goes to outdoor unit contactor. green wire goes to indoor fan. blue or brown wire goes to reversing valve on outdoor unit.
What do you do with the ground wire when installing a new thermostat that doesn't have a connection for the ground wire It's a 4 wire Honeywell thermostat Is it ok to not connect the ground wire?
That Thermostat is LOW voltage. IT does not have a ground wire. There is no need for a ground. it only opperates on 24 volts. there may be a green wire but it does not mean it is a ground
What is the difference between Razor wire and Constantina wire?
I was a soldier so I dealt with both types alot. Constantina wire has sharp little squares where as razor wire has bigger razor blade shaped barbs.
What is the difference between fuse wire and normal wire?
Fuse wire is designed to open under over current conditions. Just like a fuse.
Describe stress strain relationship for a loaded steel wire?
F = {YA(dl)}/L Stress = Restoring Force/Area Stress = {Y(dl)}/L (Strain) x (Y) = Stress Strain = (dL)/L Y : Young's Modulus A : Area dL or dl : Change in length
What is strain in physics?
Strain is the change in dimensions per unit original dimensions. For example, if your stretch a 100 cm long wire by 5 cm, Strain = 5/100 = 0.05
What is the relationship between stress and strain?
Stress is the load per unit area acting within a material. It can be thought of as the internal resistive response of a material to an externally applied pressure.Strain is the change in shape of an object in response to external pressure or internal stress. To complicate matters, strain causes the transmission of stress through an object (as in simple terms the strain causes an internal "movement" causing one part of the inside of an object to press against the material next to it generating stress in this region, this in turn can cause more strain and so on!).There are a number of differing types of strain, for example axial strain is defined as the change in length relative to the original length of an object (e.g. a steel wire being stretched). This change in shape is also called deformation. Volumetric strain occurs when an object is squashed or pulled on all sides leading to a change in volume.
What is the stress strain and elongation of a wire if it is 80cm long and 0.03 cm in diameter used to hang an object weighing 6.5 x 10-2 Newton?
The stress is 0.065 newton, plus a component at each point that's due to the weight of the wire below that point. That component depends in turn on the density of the material of which the wire is formed. The strain and elongation both depend on the ductility of the material of which the wire is formed.
How do you calculate cross sectional area of wire for young's modulus?
You could use a micrometer to measure its diameter. Preferably measure at several locations and use the average. Then cross-sectional area = (1/4)*pi*d2 --------------------------------------------------------------------------------------------------- Here is a cheaper alternative: A=V/L where, A= the cross-sectional area of the wire V= the volume of the wire, measured using water displacement. L= the length of the wire, measured using a ruler also if the wire gauge is known simply use the following formula to obtain diameter: D=.005*92^((36-gauge#)/39) As far as young's modulus calculation goes, here is the general procedure: Catalog the force applied to both ends of the wire with time. use a strain gauge to measure the axial strain with time. calculate the engineering stress using S=F/A. plot the stress verses axial strain and then isolate the elastic portion of the plot. This is the portion of the plot where the slope is constant. The slope can be taken as Young's Modulus.
Does copper wire insulate?
The insulation on a wire is applied after the wire is drawn to size.
When a wire is pulled it is said to be in?
Compression
What is a carrying wire?
A wire with some resistance and a voltage applied to it The amount of current I passing this wire is V/R
What is definition of connecting wire?
The definition of connecting wire is a piece of wire used to attach two circuits or components together. The gauge or size of the wire must be large enough to support the amount of current flow.
What is the example of zero order instrument?
Wire strain gauges are an example for a zero order instrument.
What is a current-carrying wire?
A wire with some resistance and a voltage applied to it The amount of current I passing this wire is V/R
How do you determine the gauge of a wire?
A well stocked metal work shop should have a wire guage as should your local hardware store
