I am obtaining data with a sample rate of 6250 samples/second on a digital oscilloscope. Ideally, I am obtaining a sinusoid output through a system from a sinusoid input. My expected results through the system are lower in amplitude than I am actually recording. I have some reasons for why...

on the contrary, i would say that there is a real point, but you cannot turn a line into a real point, and likewise you cannot turn a point into a line. Visually, yes, what you might say is the case, but eyes are deceiving. In reality, I would look at a point as a dot, zoom in a billion times...

it will approach one point, but never actually be one point, it will just be an infinitesimal small line, which can be halved and halved and halved infinitly, the world could be a very small place, that's my thought at least. if you look at it as a specific size point, it may eventually get to...

This may be common sense, but my brain just isn't working at the moment. If I am taking a length, L, and effectively stretching it to a new length, L+dL. I am interested in the ratio dL/L Let us say for example L is 2 mm long, and a stretched length of 2+0.2 mm is 2.2 mm. The total...

Hey FredGarvin, or anyone else, if you get some time, do you mind looking at this and telling me your thoughts or poking holes where you can: I am trying to come up with a mathematical approximation of what is happening to the resistance of a strain gauge, as sections of it become either...

Indeed, I exaggerated those numbers just to pick a random value, I am trying to get an idea for all these basics for "not so common" practice, so i appreciate the help

Let me also say, I know that just approximating the length of one of the longitudinal legs is generally enough, but i am interested in each one, not just a single one

Ok, that makes a ton more sense now. So in your example image, there appear to be 14 legs of the continuous wire (i'm assuming the solder tabs themselves represent the end of the wire?). In an ideal connection, if I say the transverse strain of the strain gauge, I am essentially saying the...

First, I am not the greatest at LaTex so if I screw this post up I will go back and try to clarify. I will skip some steps, but get the general gist of everything. Ok, I am following the derivation of the resistive strain gauge equations starting from the basic form of resistance of a wire...

I am trying to figure out a couple questions involving strain gauges. First of all, how is the gauge factor physically determined. Anyone know the process by which a company gets that. I am particularly using a Vishay strain gauge with a GF of 2.035, and indeed in practice most standard...

The probability density function of a sin wave is a U shaped distribution, let's say from -A to A, where A is the amplitude of the sin wave. The beta distribution is the closest thing to a U shaped distribution I have found when the parameters alpha and beta are less than 1. I have found a way...

I have is a distribution that is U-shaped, centered at 0, spanning from -A to A, and I want a means to model this, a beta distribution is the closest thing I have found to kinda do this can the beta distribution be adjusted to range from -A to A as opposed to 0 to 1? any other suggestions as...

so let's say I got my data by means of measurements, 4096 data points total, then i sort them into histogram form If each bin is represented by 1 value, If I divide each point by 4096, would that normalize the plot into the actual (approximation) PDF?

I am looking at values of a sinusoid, y = A sin(2*Pi*f*t), oscillating between A and -A at a frequency of 25 Hz over 0.650 milliseconds. If I find the histogram of the sinusoid, is this the same thing as the probability density function of that sinusoid? If this is not the case, what does...

I am using a cantilever beam, guided on one end and fixed on the other, (example 1b from Roark's Formulas for Stress and Strain), I have included the page from the book as an attachment. I want to determine an equation for the stress along the top of the beam. The beam is 250 mm long, 3 mm...
