"The planet gear A is pin connected to the end of the link BC. The sun gear D is rotating clockwise at ωD = 6 rad/s while link BC rotates counterclockwise at ωBC = 3.4 rad/s. Determine the angular velocity of the ring gear R measured counterclockwise." I've been at this for over half an hour and I'm getting nowhere. If anyone knows anything about Dynamics, I would really appreciate the help.

inkyvoyd · Answer

did you look at wikipedia regarding planetary gearing systems? iirc this business is VERY tricky.

anonymous · Answer

For what it's worth, I'm looking it up now. I've found a few equations for a binary planetary gearing system, but I'm not entirely sure what the variables are referring to, and the paragraph explaining it isn't very clear to me.

on wiki? this one? https://en.wikipedia.org/wiki/Epicyclic_gearing

inkyvoyd · Answer

I assume the rotational rate of link BC is equivalent to the annulus, but I am not so sure.

inkyvoyd · Answer

is equivalent or can be made equivalent as corresponding to the article...

Sorry for the delayed response. I'm kind of trying to do two things at once here. I have this problem and one thermo problem I have to do before I can go to bed. The thermo's not a problem; just time consuming.

Tried again. Still not getting it. ARGH! I just want to go to bed....
