 | I have looked up the properties of Garolite G-9 and see that its rated
tensile strength is 39,000 psi (in rod form). I'm sure if you apply a
tensile force to a solid rod, it will exhibit such strength, but I'm
wondering more about its structural characteristics in other directions.
What I plan to do is drill a small (.06") hole through the side of the rod
(0.500" dia.), near the end. A loop of wire will pass through this hole and
pull along the axis of the rod. What I'm wondering is: will the material
have a tendency to split and let the wire break through? Or can I count on
it standing up the same as a metal with a 39,000 psi tensile strength?
Has anyone in the group dealt a lot with Garolite who might be able to help?

| your tensile strength is probably not going to be the 39ksi listed for
that particular alloy. there are certain modifiers that come into play
when you have a force applied at a hole, such as hole radius. look in
any mechanics of materials texbook to see how to calculate your actual
tensile strength. also, your load may be limited by the wire you're
using, in which case you wouldn't need to worry about the garolite rod
failing.
