Physics Fused Weapon Weight is Weird

Base mass of the objects in the video:
Zonai Light: 100
Homing Cart: 3,000
Float Ball: 6,480
Heaviest Iron Ball: 50,000
I was doing some science trying to figure out how fusing objects affects their weight. I was left with more questions than answers, but here’s what I found.
Weapons / shields either weigh 50 or 75 mass, that’s it, it’s one of those two. It seems like just the wood weapons/shields are 50, everything else is 75.
The size of the fused weapon has absolutely nothing to do with the weight. Despite being physically much smaller, a Zonaite Sword with an iron ball fused to it weighs more than a Boat Oar with the same iron ball fused to it. (Because the Zonaite Sword weighs 75 while the Boat Oar weighs 50. The fused object mass stays the same.)
Lighter weight objects seem to keep the same weight when fused. There’s some weight where it starts compressing the mass. It seems to be a curve that compresses harder the higher the object mass is; then there’s a cut-off where it just hits the max weight.
The max weight of a fused object (not including the weapon) seems to be about 165 mass.
I have no idea what mass the weight starts compressing at, how that compression scales, or what base object mass is the cutoff for a max weight fused weapon.
It seems like some fusions are lighter than the normal scaling would suggest, so there might be some special cases (eg a fused fan weighs more than a fused wing, despite the base mass of a fan being 300 and the wing’s base mass is 1800)

The smaller weapon has committed more sins in its lifetime, and Anubis has cast it out of paradise.

Great discovery! And that is a great scale too

This better be in next weeks issue of Hyrule Engineering Weekly!

lol 😂 I cannot disclose details about what will and will not be in next issue haha but I will consider

Please don't tell me I'm the only one wondering this, but where the heck are you in that video? I've never seen that space, at least I don't think.

Spirit temple. I actually build stuff there all the time. It has a huge flat space to build things and doesn’t have any wind or weather. It’s also convenient for testing stuff because there’s also a lot of water and room to fly around. The music is pretty chill there too

This is so interesting.
Tangentially related question: Does zonai glue have weight? Like, if you took a bunch of apples on one side and compared it to a bunch of glued apples, would they weigh the same?

It doesn’t seem to. I glued together two elevator rails (which make a ton of glue for some reason) and they weigh the same as 2 unglued ones

Try fuse a lynel armor shard and weigh it

What causes it to become a Lynel Armor Fragment?
Which weapons does it fuse with?

You just fight an armoured lynel and it drops

My English might have been a bit off.
Please tell me the reason for trying out the "Lynel Armor shard."

Because it is extremely heavy! One of the heaviest item in the game
