instead of a compromise, you may wish to rephrase it as a tradeoff

I have measurements of m, L, Y and f there is no relationship between Y and m, Y and L , F and m, F and L there is correlation between Y and f Could the lack of correlation in Y vs m and Y vs L indicate that in my system, EI is the most important predictor of Y and by extension f ? I guess...

Hi For a cantilever beam with a load at its end, flexural rigidity is: EI = m*g*L3 / 3Y Where m=mass, g=gravity, L=length of beam and Y=deflection the natural frequency is f = 1/(2∏) * √ ( 3EI/mL3) Plugging in EI to the formula for f reveals that f depends only on the...

Hi, thanks for your response. I have already done pairwise cross-correlation and 'shifted' all 3 signals to maximize 0 lag correlation. Here is the problem in more detail. I have an accelerometer (reference signal) on a plate that is fixed to an electrodynamic shaker. The electrodynamic...

Hello folks, I am an out-of-my-depths biologist looking for some guidance. I have a reference signal and 2 other signals. Signal 1 independently measures the same event as signal ref but signal 1 generally underestimates signal ref. Signal 2 is measured the same way as signal 1 but but it...
