Either preloading- so they're stretched out as far as they will be at full load, or measuring the stretch, and then building/mounting that much short will work. Second option is easier at these kinds of forces.I was thinking that when I glued the tension members while in tension I would add the little bit of 'preload' angle that I was looking for... Obviously didn't work Not quite sure why they stretched so much, is there any specific cross sections of wood that tend to stretch more than another?
I've been steadily increasing. I started out with about a score of 150 and am up on 430 now.For anyone in division b, what scores have you been getting.
777 is pretty good for div. B from what I understandWOO HOO! Went to regionals on Saturday! We did much better than anyone else, but there was some mix-up, and we did not even place! We talked to the event coordinator and they looked over the results today and it turned out we did get 1st place! We got 777 for our score for division B (that's relatively low but God willing, it will get better ) Thank God we did good, and thanks to everyone who helped me!
