Hi Pongo
I'm having to model the motion based on the 1-minute interval data (I'm using a polynomial) and then interpolate using the functional model to get down to the second-level. It's not ideal, but it's the best data I have.
Yes, the perpendicular bisectors would intersect at a pole of...
Hi Stephen, thanks for your reponse.
Thanks for the suggestions about simulations. I have been considering starting down this path.
The true rotation does not involve a stationary axis, the axis is experiencing translational motion as well. The rate and even direction (CW or CCW) of...
Hello all,
I'm currently a undergrad university student doing research and I'm anaylising some position data.
The data is a time-series' of Eastings (x) and Northings (y) for two points (P1, P2) on a rigid body in motion (T, E1, N1, E2, N2), with a position reported every 1 minute. I know...
Hi All,
I'm struggling with finding a solution to an adjustment I'm working on. Thought someone else may have some thoughts?
I have a kinematic time series of X,Y positions for two points (X1,Y1,X2,Y2). I know that the two points were a distance D (e.g., 100 m) apart from each other (the...
Thank you for the reply.
Okay, so it won't necessarily rotate around the center of the rigid object, it really depends on the distribution of the mass (the shape) of the object? One part of the object may be shaped in such a way that it generates more drag, etc.?
If a large, stable floating object is placed in the ocean, free floating, and the tides and currents act on that object causing it to rotate, will it always rotate about its center of mass?
Thank you for your response Steve. I apologize, my terminology was clearly incorrect. I come from a surveying background, and was trying to frame the question in physics terms.
What I actually have are two coordinate pairs—so four points in all—the first two describe a line A and the second two...
Vector A must stay stationary. Vector B must be rotated around a point in the plane that will make it fall directly on top of vector A.
Picture two vectors of unit length lying in a plane in different directions and locations. Where do you place the origin of rotation so that rotating vector...
Given two 2D unit vectors (A and B) in different directions and positions in the same horizontal plane, is it possible to determine the origin (point of rotation) required to make vector B = vector A (same position and direction)? All this assuming that vector B is a rotated (only) version of...
