Today I finally stopped putting it off and started my science fair experiment for the 2018 STEM fair! I worked today for EIGHT grueling hours and managed to collect twenty data points despite multiple errors in testing (mainly brain-farts as I was getting tired) As follows is the procedure I used today collecting data for pullout force. Not quite sure how I'm going to cast my hypothesis yet or incorporate my results but its all a big work in progress. :)
1.) CAREFULLY cut testing wood into 4x4 squares inches. (all wood was 1&1/2 inches thick)
2.) Drill a 9/32 hole centered in a (each) board.
3.)Start threading the 3/8-16 Hangar bolt into the pre-drilled hole. 
4.) Finish up threading with a drill. 
5.) Take a pre-trail reading on the load cell. 
6.) Insert the board-bolt complex and use washers to span the gap to the other side of the instrument. Finish up by hand tightening the nut until a small amount of pressure is seen on the digital readout of the cell. 
7.) TIME FOR THE BIG GUNS! tighten that junk until the wood fails (from what i've seen either the threads strip or the wood splits.)
8.) take a post tiral reading using the "peak" (maximum tension the wood was able to withstand.) 
9.) Remove the bolt the repeat.
PSA: ALL READINGS ARE IN AMERICAN POUNDS
Again not quite sure what to do with the results but today was mainly for number crunching and I left the workshop so exhausted when I was done I even forgot to snap a picture of the finished data sheet. It was a super long day and i'm also ridiculously sore from swimming practice. Anyway, LET ME KNOW if you as a community are interested in me uploading a steem version of the ENTIRE PROJECT, including graphs, research, and analysis when its all said and done. What about a site wide science fair of our own? Here's a cool picture from my snap story that shows today's work including a block or maple that held OVER 4,000 POUNDS!!!
