i need help with Silicon Carbide?

Question

hey, pls help me. I have a yarn of silicon carbide..and i cant do any testing on it. all i have is the thickness of each yarn and the length. how do i calculate strength or failure rate or anything else that can tell me if its good or not.any suggestions? im stuck.

Answer 1

Better than that, look up some standard tables, be careful with the yarn, SiC is extremely hard.

Answer 2

Hang a spring scale from the ceiling or the underside of a table or stand. Attach the yarn to the scale and hang various weights from the yarn to test the weight at which the yarn breaks.
