He gave so detailed and complete responses and he understood the whole process of build a balsa structure.

Also if you can I would ask. If it's written in pen it should be fine...

He was known as Balsa Man on the Balsa Structure Forums.

I'm a little disappointed in you TheChiScientist. :( He was the powerhouse behind the Towers forum, and he is the reason me and many other competitors can actually build decent towers. But no hard feelings ;) .

I also joined kinda late but I read a bunch of his posts and they were like super detailed with a TON of info. All of his posts were really long with a lot of building advice and replied to pretty much every question asked with a huge paragraph with explanations and stuff.

Was the testing device for towers tilted? I heard that many teams go significantly less than they expected and broke in the same place. Gelinas also got less than we were expecting. Is this a coincidence?

My tower did terrible too. It scored 500 less than expected. I wouldn't be surprised if it was tilted.

Ours seemed to break a little earlier than expected. One side of bucket filled faster/higher.

Does uneven loading matter? As far as I know, because it is ultimately hanging from a chain with a pivot point at the connection to the bucket, this shouldn’t matter. I could be wrong though, feel free to correct me

I don't think it is entirely correct that uneven loading doesn't matter. Yes the load is always transferred from the chain to the loading block which is a fixed location. So yes the load is always transferred at that location. However, The chain will always extend from the attachment of the chain to the load block, to center of gravity of the bucket. And center of gravity of the bucket will always seek out to be directly below the point of attachment of the chain to the loading block (center of load block). If the bucket is unevenly loaded, the bucket c.g. will shift over to the side that is heavier. At this split second of time the chain is not directly vertical but is at a small angle. Therefore, the load in the chain is at an angle which will give it a lateral component in addition to it's vertical component. This lateral component will also transfer into the tower at the attachment of the chain to the loading block which could affect tower performance. This only lasts for that split second until the bucket c.g. swings back into place under the center of the load block.

Oh yeah completely agree my tower broke at 7175 grams, it was designed to hold 12+ kilos. Scored 1533, what can I say?

Also yes the sand did not fall in the middle. It probably would have been better if teams loaded by hand :lol: .
