Re: Covid-19 and Nats/States

I heard an unsubstantiated rumor this weekend that Texas may have cancelled their state tournament as well... Budgets at the school level are always tight and paying out as much as $250 / team for registration is a pretty big hit for most teams. I'm wondering if any of that get returned for that sta...

[/quote] Our regional was won with a 15 gram-ish boom... Does anyone know what won theirs? I am fairly confident that it'll be impossible to have an 8-gram boom and hold it all. [/quote] Sergio, I'd need to disagree with that statement... Just this week, I saw a 7.67 gram boom carry 14.974 KG... I'm...

Re: Boomilever B/C

[ [/quote] Despite the debate of 1/16 square v. 1/32 square v. 1/32x3/16 v. 1/16x1/8 (what I use), wouldn’t a rectangle size (despite the obvious heavier mass) just be more efficient because the flat side gives a larger surface area to connect tension to compression on the distal end? Last season th...

Re: Boomilever B/C

There are ways to distribute the load transfer to less dense members so they don't "blow out" the lighter wood.

Re: Boomilever B/C

if one were to use 1/16 x 1/16 bass for tension from a 24" stick. What weight would be ideal for a 24" stick 1/16" square WILL hold full load on Div B designs... Gets a little sketchy on Div C designs. We buy our 1/16" squares in 48" lengths ranging from 1.07 to 1.57 grams. Even the very lightest h...

How many trusses are recommended for full load held? I don't want to over/under build on how many I'm making :|
You cant design in a vacuum. It depends on the compression beams. The smaller/ lighter they are, the more support is required.
