Centripetal force is in a straight line, towards the center of the circle. Vin pulled the gate in a straight line, then moved to the side and pulled in a straight line, causing it to curve.

It acts almost exactly like Shardmetal?

So in a lot of the scenarios. Those in which the Mistborn doesn't just decide to steelpush to the side and make you miss completely. That's what centripetal force is. If you need an example of what Vin did, get a string and tie something on the end. Then move that thing in a straight line, like Vin did when she initially pushed the gate, and hold onto the string from the side of where the object at the end initially was, like Vin did when she twisted and pulled on the gate. The result is circular motion.

"You want to run into the darkness and get yourself killed, be my guest."

It is steel that is as invested as Shardmetal.

And if the Mistborn hits you before you finish? Sazed explicitly said that the gate swung around the courtyard as if attached to Vin by a chain. And it moved in circular motion, requiring centripetal force.

1. The end result is feruchemical because the feruchemical attributes that you've stored in the metal "key" it to that feruchemical power. 2. Those things are weird. It might make memories more clear, or maybe just replicate them. 3. Atium stores youth, not age.

"That's good." Nameless pulled his sword from its sheath, eyes not moving from the darkness in front of him.

Azure's blade is Shardmetal. It's visually indistinguishable from a normal Blade, and functions almost the exact same way, only with a Nalthis-style kill effect instead of a Roshar-style.

If a regular human sees themselves as a chicken, they will not become a chicken. If everyone sees a sword as a shield, it will not become a shield. Investiture allows one to perfectly match their Spiritual aspect, held back only by their Cognitive aspect. And do what? Abandon the Soulcasting attempt to block? Vin swept the gate around the courtyard in a circular motion, meaning she experienced centripetal force. Assuming the gate was 700 Kg, the radius of her swing was 13.42 meters (based on the 1,000 soldiers that fit into the square), and the velocity was 10 meters/second, Vin had ~5,216.1 Newtons of force applied to her, or about a thousand pounds. (This is probably a low estimate. Vin was sending Koloss flying, and considering that they can get up to twelve feet tall, meaning they'll be upwards of 300 Kg each. Sweeping through groups of them with a gate that weighs less than twice as much as a large Koloss isn't going to result in what was described in the book.)

We haven't heard that there's any limit on the size an awakened metal object can be. They just make it regular swords because those are the most practical in all situations.

Because the spiritual/cognitive aspects have no influence on the physical unless Investiture is involved. They don't need shadows to dodge this. And an offensive would work, if they could close the distance in time. Get a hand on the Lightweaver before they summon their Blade as a wall, and it's over. True. The force exerted on Vin due to swinging a thousand pound weight around is more than a thousand pounds, and Duraluminum Pewter is easily in the realm of high 10s so low 100s more powerful than normal Pewter.

It is a Shardblade, functioning very similarly to a normal Blade aside from an inability to form a Nahel bond. That means it is on the same "Investiture tier" as ordinary Radiant spren.

And the Shardblade?

Is there a reason it's not exactly perfect? The Mistborn is not going to stand still when they can tell (via bronze) that the Lightweaver is soulcasting something. Moving quickly is the best way to avoid an attack like that. We don't see Shallan hitting the ground. She may have been grievously injured and healed from it afterwards. She moved it with enough force to send Koloss flying. The thing must've weighed at least a thousand pounds (and that's really lowballing it), and she sent it through the Koloss with enough speed to scatter them like bugs.

"For me, at least. Haly, can you still use your powers?" @Ookla the BlowUpperOfStuff

I agree. As I said, it takes only 1,000 breaths to create a sentient Shardblade. Yes, they're more limited and possibly less invested than the spren we see in SA, but they're at least in the same ballpark.

My explanation is: Soulcasting Stormlight cost is based on mass, because mass is what a Soulcaster is transforming. Your explanation is, as far as I can tell: Soulcasting Stormlight cost is based on volume, because Soulcasters perceive objects with higher volume as being more difficult to soulcast. The energy to actually transform the object in the physical realm comes from the spiritual realm. Is my summary of your explanation correct? I agree that Radiants will be better at soulcasting, but even if they're 10 times better than a fabrial soulcaster, the Mistborn will have time to dodge. They hit a wall, then are hit by a wall. Not a fall. Renarin was crushed by a Thunderclast multiple times, and he had a perpendicularity's worth of Stormlight. Beyond that, Windrunners are the only people we've seen protected from falls, are they not? Description from WoA: Again, that was without Duraluminum Pewter.

I'm not arguing that spren aren't made out of Honor's investiture, I'm arguing that they don't take Stormlight from spheres to make spren because they would need too many spheres. Stormlight is less dense than breaths.

Which assumption is simpler? Fabrial Soulcasters that as we have seen often work in groups, and take time to Soulcast stuff. Punch. The Radiant is smashed against wall, then their Shardblade hits them and crushes them into it further. And how did Vin survive moving the gate? That's multiple times more force than she used breaking that dude's head in, and she was fine afterwards.

Because it's in solid form. Spiritwebs are vulnerable, as is gaseous investiture.

"I... can't touch the Source."

"Don't worry. I think I can handle anything they try. As long as they don't-" Nameless cut off as the orb of light he'd summoned winked out. He stared at the space it had been in, shocked.

Yeah, most spren are a mix. Anti-Stormlight would still most likely kill spren that aren't as pure Honor as Honorspren, but they are a blend. And all of Adonalsium's Investiture got assigned to the different Shards though, so there aren't any Adonalsium-spren running around.
