so im in this comp tomorrow and im going to be at the zoo and our tower is pritty sterdy intill my partner brock it we fixed it by puting braces on the cracks and regluing it :):):):)
@wafflepoints do u happen to have ur design or general idea of dimensions? height of entire tower, height of base. thickness of wood in each component etc... please let me know!
hi..nice job wiht the tower..can u give me step by step instructions to how u build it..i have to biuld one like that for physics...but instead of u putting weights in, i have to sand in the bucket..aslo the hole that teh tower will be placed in is 20cm.
I gave some nice tips earlier... I can't do step-by-step instructions, as the rules change every year... and I'ld like Northampton High School to win...
and we used sand for the actual event, too... what we had down in my cellar for the first prototype testing wasn't sand, it was weights
2. try for simple triangle and prism shapes if possible (We HAD to build the base wide and top thin, if not, this thing would've been a prism or shaped like one of the twin towers, triangular trusses are very strong when u have the joints connected right)
3. make sure the bucket isn't swinging when you put the weights in. I tower handles compression a LOT better than twisting and shearing and stuff. The swinging bucket there (even though it doesn't seem big) maybe halved what we could hold
well, I feel sort of bad helping out another school, but basically there are like 3 things to keep in mind:
1. use very large area, flat connecting surfaces that perfectly (enough) face eachother, with just a little glue (a little cyanoacryllic glue goes a LONG way)
2. try for simple triangle and prism shapes if possible (We HAD to build the base wide and top thin, if not, this thing would've been a prism or shaped like one of the twin towers, triangular trusses are very strong when u have the joints connected right)
3. make sure the bucket isn't swinging when you put the weights in. I tower handles compression a LOT better than twisting and shearing and stuff. The swinging bucket there (even though it doesn't seem big) maybe halved what we could hold
wow, if you couldn't tell, we were testing this in a cellar. What we had was some mixed weights, some given in kilograms, some in pounds. I did a rough estimate at the end of the video in kilograms.
the final design looked close to that, and we glued it better. I forget the exact weight (somewhere around 15-20 grams), and it held 13. some kilograms.
and yeah, I didn't expect it to explode, it was pretty funny in a depressing kind of way, and now I know why safety goggles are required.
The final tower was much stronger, significantly lighter (after analyzing this video in slow motion), and we were much more careful loading weight and got 6th place at regionals (out of 26, not that great, but not bad for first try at this event)
I was the guy holding the camera, and one of the 2 people who made the tower. This obviously wasn't the final tower, and if you look closely, you can see why it broke.
The bucket holding the weights was swinging back and forth, and towers are never really meant to take forces from that angle.

what is the best wood to use?
Narutofan1000k 5 months ago
@Narutofan1000k I think the standard is balsa wood, but don't quote me on it. I'd do more research
saphie3243 4 months ago
@Narutofan1000k balsa wood its light, for this year the lighter the tower that can hold the most weight wins

fail. }:D

Do you think it's better to use square balsa wood or round?

@prvmonkey definitely square...

To be honest, it's useless for it to hold over 15kg.

That's cool waffle. As long as your tower is light and there is no spelling component to the competition, you should do well.

Where are this guy's goggles? And pounds? In Science Olympiad? Honestly...
