### Limits of Euler-Bernoulli Beam Theory for Wide Plate in Flexure?

I'm looking for established limits or rules of thumb for the validity/accuracy of Euler-Bernoulli beam equations for particularly wide "beams". For example, a simply supported rectangular ...

### Does pressure in a centrifugal compressor increase along the path of the flow?

Euler turbomachinery equation doesn't include a term for changes in flow area. But, an centrifugal impeller (not the volute) has increasing flow area along the path of the flow. Is the pressure ...

### Euler's formula with different coefficients and constants

Hi and thank you in advance. I understand that one of Euler's formulas states: cos(x) + isin(x) = e^ix I know that if you were to have the same coefficient ...

### How to plot quaternion constraint equation vs time

If K = q1^2 + q2^2 + q3^2 + q4^2 and K0 = q1^2 + q2^2 + q3^2 + q4^2 = 0 + 0 + 0 + 1 = 1, how to plot K-K0 vs time graph. K is the quaternion constraint equations where the quaternions are changing ...
