Will depend on the boundary conditions and your need. Can you post a pic of what you trying to do or looking for.

Deepak,

First, Thank you for the Birthday greeting.
Another year, another challenge.
The attached .avi files show what I an trying to study.
I need to determine what applied force it would take to tip each version. (The force bing applied at the top of the unit)

Karen

wouldn't a free body diagram be easier.
You know your CG * x (distance to tipping corner) / y (veritcal distance from floor to force) should give you a force required to tip it. Any reason to make it more complicated and do analysis, other than for fun?

Dorian,

Fun yes, but also because the company I now work for had just transitioned to 3D with little training.

Often when completing complex surfaced models, they are refered to by co-workers as "pretty pictures".

I am trying to make them understand that this is more than just a program for making 2D drawings.

The don't understand the importance of utilizing all of it's capabilities. We have a "premium" licence, yet the Photo-works, Analysis, Motion, Simulation, 3D Render, and PDM have been ignored.

Damn 2Ders.

Frustrated,

Karen

in that case since you know from the free body about what force it will take you could set up a motion simulation and place a force at the top with a linear ramp from 0lb to 5lb above what you think it will take. Then you could put and applied force sensor and a reaction force sensor so you will be able to plot applied force on top vs the reaction on the side that is lifting. Is that what you were looking for or are you already done with it.
ps. did you use say rubber on steel friction force between the components so you can see if it will actually tip vs slide?

Oh no Dorian,
I never give up tying to extoll the power of the program.
I wil take your suggestions in tommorow.
I have been a Pro-E junky for years. Thought there was nothing better.
I've had no formal training in Solid Works, but have delved into any tutorial or guide I could find.
I purchaced Matt Lombards Solidworks Bible when I started this job. Dang this is cool.
I'm currently going through Matt's Surfacing book, and waiting for Cosmos and PDM to ship.
True Solid Works Geek,
Karen
