What is the difference between displacement and true power factor?
'Displacement power factor' is the technically-correct term used to describe the cosine of the phase angle (i.e. the angle by which the load current leads or lags the supply voltage) due to the reactance of a load. Usually, when we talk about the 'power factor' of a load, we mean 'displacement power factor'.However, another type of power factor can exist in a circuit, due to the presence of harmonics in the current waveform, due to non-linear loads such as SCR rectifiers. This type of power factor is temed 'distortion power factor', and may be corrected using filters.So, the terms 'displacement' and 'distortion' are used whenever it is necessary to clarify these different types of power factor.
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 meant by engine displacement?
Engine displacement refers to the total volume of all the cylinders in an internal combustion engine, typically measured in liters or cubic centimeters (cc). It indicates the engine's size and capacity to draw in air and fuel for combustion, impacting its power output and efficiency. Larger displacement often correlates with more power, while smaller displacement engines may prioritize fuel efficiency. Displacement is a key factor in determining an engine's performance characteristics.
Is it advisable to correct the power factor to unity?
power factor depends on the load being fed if the load is entirely resistive power factor will be unity ..if the load includes an inductor or capacitpr due to phase displacement between v and i the pf will be lag or lead respectievly
What is a non positive displacement compressor?
Well it is very important factor in fluid mechanics. The term comes often in compressors and Pumps. Displacement means change of place( Fluid ), Positive displacement means at all points of operating the discharge will be the same where as the discharge in non positive displacement varies at various operating points. For clear idea on the above compare the reciprocating pump with centrifugal pump at various operating points (by throttling) discharge valve).
When displacement per unit time is tripled the velocity increases by what factor?
If displacement per unit time is tripled, velocity will increase by a factor of 3. This is because velocity is directly proportional to displacement per unit time in a linear relationship.

What is the factor on which lateral displacement depends?
The lateral displacement of light depends on the refractive index of the material through which the light is passing and the angle at which the light enters the material. The greater the difference in refractive index between two materials, the greater the lateral displacement of light.

Why can age be a contributing factor in the formation of a bunion?
Age has also been noted as a factor in developing bunions, in part because the underlying bone displacement worsens over time unless corrective measures are taken.
Is it advisable to correct the power factor to unity?
power factor depends on the load being fed if the load is entirely resistive power factor will be unity ..if the load includes an inductor or capacitpr due to phase displacement between v and i the pf will be lag or lead respectievly
What is more accurate volume displacement or dimensions of an object?
Either can be accurate. Depends on how accurate your measurements or equipment is. The shape of the objects could be a major factor, too.
What are 3 useful displacement reactions?
Two types of displacement reactions are known:- single displacement- double displacement
What is the result of adding a displacement vector to an another displacement vector?
another displacement
What is the only case in which magnitude of displacement and displacement are exactly the same?
The only case in which the magnitude of displacement and displacement are exactly the same is when the displacement occurs in a straight line. In such a scenario, the magnitude of displacement (distance between initial and final positions) will be equal to the displacement (change in position) as there is no change in direction.
How do you get displacement from a displacement graph?
To calculate displacement from a displacement graph, find the area under the curve. If the graph is a straight line, you can subtract the initial position from the final position. If the graph is not a straight line, calculate the integral of the graph to determine the total displacement.
