Paul curious as to what your recommendation is. I'm planning on doing some
testing of a structure similar to an engine mount. I was going to try your
1/4 scale balsa model idea, but how do you scale the load? 1/4 of the actual
load seems much!  Maybe there isn't a good way to do this?

Some have suggested building a test mount with PVC pipe, loading it, and see
how it fails.  Might give you an idea about your design.  Richard Finch's
welding books suggest hooking the final mount up to a car bumper and lifting
the car.  Nothing beats a real load test, I suppose.

You won't learn very much more with the PVC pipe model than you
would learn with the 1/4 scale 3/16 balsa stick model.
Probably less as you must apply much higher loads to see what is
defelecting where.

Richard Finch got the car test from our web site years ago.
