What is the shape factor of the circuit?
The shape factor is the perimeter of the contour around the area of interest divided by the square root of the area. It is a component of the formula used to calculate the coefficient of error (Coefficients of Error). Stereo Investigator does not calculate a shape factor; instead, it defaults to the value 4.0.
What is meant by shape factor?
Shape factor refers to a value that is affected by an object’s shape but is independent of its dimensions. It may refer to one of number of values in physics, engineering, image analysis, or statistics. In physics: Shape factor, or shaping factor, a performance measure for filters such as band-pass filters.
What is the ratio of shape factor?
i.e. Shape factor is the ratio of Plastic Section Modulus to the Elastic section Modulus. Shape factor of every type cross-section is always greater than 1 because it represents the reserve strength of material beyond yield point to reach plastic stage.
What is the shape factor of I section?
Shape factors can be found in relevant books and vary between 1.12–1.18 for I sections, equals 1.27 for a hollow circular section(pipe), 1.5 for a rectangular section and is 1.7 for a solid circular section.
What is the purpose of shape factor?
The shape factor explains the angle ratio under which two surfaces appear with respect to one another. Its applications include heat exchange computations caused by thermal radiation, lighting engineering, and the parameterization of isothermal knot models in space thermodynamics.
How do you calculate shape factor?
How to Calculate Shape Factor
- Measure the area of the face of the object where the load is being applied (load face).
- Measure the cumulative area of all faces that can bulge (i.e., perpendicular to the load face) when the load is applied (bulge face).
- Divide the area of the load face by the area of the bulge face.
How to calculate the Q factor of a resonance circuit?
Q = P stored /P dissipated = I 2 X/I 2 R Q = X/R where: X = Capacitive or Inductive reactance at resonance R = Series resistance. This formula is applicable to series resonant circuits, and also parallel resonant circuits if the resistance is in series with the inductor.
What does a series resonant circuit look like?
A series resonant circuit looks like a resistance at the resonant frequency. Since the definition of resonance is X L =X C, the reactive components cancel, leaving only the resistance to contribute to the impedance. The impedance is also at a minimum at resonance.
How is the impedance of a resonant circuit determined?
A series resonant circuit looks lik a resistance at the resonant frequency. Since the definition of resonance is X L =X C, the reactive components cancel, leaving only the resistance to contribute to the impedance. The impedance is also at a minimum at resonance.
How is resonance maintained in a short circuit?
Non-short circuit method to maintain the resonance, using a transformer and current generator. The current source is typically a square wave, in phase with the resonant inductor voltage.
