Both the bar and the rod where tested by the trifilar method. However the rod was placed under one more test, the knife edge, results for these experiments can be seen on table one. We also noticed that there was a great difference in our results, that is the ones obtained experimentally differed from the theoretical ones by about 0.015.For instance the result that was gotten by the trifilar method for the rod ...
