    Determining Elliptical-ness of Data: A Statistical Approach?

    In what I'm doing, after applying a transformation I would like to see the data in some sort of ellipse (circle valid of course). Often when the transformation is bad, I get plots representing Xs or ellipses with Xs through them. I was hoping for some statistically valid method to do this, but...

    Determining Elliptical-ness of Data: A Statistical Approach?

    "Elliptical-ness" of Data I have sets of data that ideally should be constrained to elliptical bounds. I am looking for a method to see how elliptical a set of data is. My inital approach involved mean-centering and normalizing my data, calculating the angle of the point relative to the...

    What Calculations Are Needed to Achieve Equilibrium in These Statics Problems?

    Sorry, N_D was an internal force from the collar. Thanks anyway, but I managed to figure this one out.

    What Calculations Are Needed to Achieve Equilibrium in These Statics Problems?

    Ok, the first problem is easy, I just forgot to get a perpendicular distance to the force, so it works fine now. As for the second problem, I was thinking about just balancing the Fx, Fy, Ma, Md, and Me, but that doesn't seem to work either. Any suggestions would be appreciated.

    What Calculations Are Needed to Achieve Equilibrium in These Statics Problems?

    Hi, I have a couple of questions from a statics assignment that I'm in need of help on. Here's what I have so far: http://216.170.11.226/pub/6131.jpg Two rods are connected by a slider block as shown. Neglecting the effect of friction, determine the couple Ma required to hold the system...
