EDIT: I solved the provlem, if anyones interessted, PM me.
Old Post:
I got down to some formulas:
Calculations for the Train:
Y-Axis Velocity
SIN(270-Position)*0.5 m/s
where position is the difference in dagrees from startingpoint to where it is now.
X-Axis Velocity
COS(270-Position)*0.5 m/s
Drawer Y-Axis is 1.2 m/s
Here a screenshot of the Diagramm and Spreadsheet.

hmm...from the looks of the problem, you want to calculate the length of a line that looks something like this:
i need to spend a little more time to help you more but this should be helpful, or you already knew this...
you just need to figure out, how long one of those loops is. The straight line distance between a and b represents the change of position of the starting point of the train on that circle track so that may help you to determine distance..calculus seems to be involved because I can't think of another way to calculate arc length... |

How do I calculate the lengh a toyloco goes, if it's on a circle track, in a drawer, wich is pulled by someone.
The Loco drives with Vu=0.5 m/s on the circle, the drawer is pulled with a velocity of Vk=1.2 m/s
The radius of the circle is r=0.3825 m, and I have to draw (with excel or stella V.8.0) the line it draws if it goes once around the circle.
I have the V for the X and Y axis (the drawer is pulled in Y axis) for every 5 |
