For curved motion (but not simple circular), is the linear acceleration that can be plotted the tangential componant only? How would the centripetal acceleration componant be factored in. I don't think the angular acceleration plot would apply.
If you select "Linear Acceleration" in the results PM, you get the options of "Tangential Component" and "Normal Component". Those will give you the two components you are looking for. Which version of SW are you using?
I can't find anything on this regarding centripetal acceleration. You may have to calculate it yourself using v(t)= v(t) / v(t); u(t)= v(t) / v (t). Cirular motion is a completely different equation than centripetal acceleration. I found this link, but I don't know how closely that will calculate what your looking for:
Where centripetal equation a=v^2/r
Do you have an image of the force you are trying to find?
Hope this helps out.
Thanks for the input. I figured getting the linear velocity from the plot and estimating the path radius (from the trace path plot) to calculate V*V / R and then add it to the linear acceleration from its plot (at key points in the path). But I wanted to make sure the radial (centripetal) portion of the acceleration was not already included in the linear acceleration plot or that there wasn't another way to get it out of the software. Seems like the software should provide both tangential and centripetal accels.
The link you provided is part of simulation and looks like it applies to circular motion as you noted.
Sure! I agree with you completely that the software should include tangential and centripetal accelerations, especially when using Motion. Maybe they will comeout with something like that in SP3.0.
Thanks so much. It works. Frank
