I don't think I can show you a diagram, but I can try to explain it better:
I am applying force to a lorentz force motor which has a displacement transducer in it which produces a change in current when the height of the motor increases and decreases (you put your foot onto the plate of the...
Hi,
I'm trying to calibrate a voltage divider circuit to measure force. I have measured the current output at two different weights, converted the weights to forces using "f=mg" and calulated a gradient from that using "y = mx + c" as well as the constant.
However, I don't feel what I did...

Hi,
would anyone be able to explain how to evaluate a function using orthogonality (i.e. using orthogonality to solve a definite integration problem with sines/cosines)?
Thank you
