Thanks! found a nice little applet on line. http://emweb.unl.edu/Mechanics-Pages/Nicholas-Loomis/index.html

Thats nice! But yes you are correct in the mass production assumption. It would be quite hard to control the density to achieve that level of accuracy, also because the liquid will change slightly between use cases. This is one reason that I was trying to use a carrier. My hope was that the...

Is there any equation to measure the percent of difference?

This is just a section of a larger beam. I was curious if the different angles of the truss arms (shown in jpg) increase, or decrease, the strength of the beam and can it be quantified. Thanks for the reply!

All things considered equal, would one of these truss structures be stronger than the other? Consider all heights equal, load equal, arms dimensionally equal, etc.. Just going off the angle difference of the triangles. Oh... if there is a difference in strength, how can you calculate that? Is...

I can't use any external forces. Only gravity and the shape. I can't get too specific about the project, but the basic premise is that I need to release a dye/ink in fluid , in such a way that it will give the best overall consistent color throughout. So I was going to apply a water soluble...

So I'm not sure if this is the right place - and its a crazy question - but I am trying to get something to spin and/or flip when I put it in a beaker of water, just by its own weight and gravity. I have tried a maple seed shape, propeller shapes, simple curls, sprials, Rocchetti pasta shapes...
