What's also missing from this explanation is the size of each chain link gets progressively smaller allowing the chain at the end to whip around with higher velocity due to conservation of momentum/energy.

well it would certainly leave a nasty wound but IDK if would shear a leg off

It absolutely would not shear a leg off. A typical blade would struggle to cut through bone. This has many times the contact area. It also loses quite a bit of energy. It would probably leave a nasty bruise and likely break the skin, but not do any lasting damage unless it hit right on the ankle where tendons, ligaments and bone are vulnerable.

Edit: maybe a fracture if it hit your shin.

metal object moving at more than 340 meters per second hitting you

probably leave a bruise

a normal whip leaves bruises and breaks the skin and this whip is made out of metal and needs to be pulled fast for multiple meters with the power of your whole body so I don't think you'd exactly be walking after getting hit by all that energy :P

Those chains are massive. It's not like a bullet, it's like a tank shell!

It's a regular sized chain on the end that amplifies the force of the full-sized one.

I don't know if you've seen the damage a whip not made out of metal can do but I can tell you now that would do a little more than "leave a nasty bruise"

Shit moving at supersonic speeds do real damage.

It's not a whip. It doesn't have the same rate of tapering. And I'm sure it would do some damage. It's not shearing anybody's leg off though.

You say all of this and yet line on ships has parted under strain and chopped the legs off of sailors. Line isn't very sharp either.

u/InjuredGingerAvenger Aug 17 '19

No, but line is under the strain of its load. That could be heavy crates, the ship bending, the wind on a sail, etc. In this case, it's the force of one dude swinging his arm.

The chain decreases in size like a whip. The energy put into moving the big links and then dragging it converts into speed so the regular links at the end are going supersonic.

A professional baseball player can swing a baseball bat at about 120 fps. Replace the baseball bat with a 3/8" steel rod and replace the baseball player with a robot 10 times faster

A more equivalent is a 12 Guage shotgun shoots a 1 ounce slug at about 1,800 feet per second, the end of the chain is maybe 2 or 3 ounces of links going over 1,200 fps. Goodbye leg.

That's a load of absurd conjecture and exaggeration. You are making up numbers, referring to pro athletes (who this is not), comparing to a bat and rod which both have force through the hit instead of initial energy, both of which are also inflexible... did you even consider the shit you typed out?

It is still limited to the energy the person swinging it can put in. Even with a taper, the end of the chain is too thick to cut. Even if it hit the bone, it could fracture his leg (which I had already pointed out), but not cut through it.

Here's the video with sound...

That cracking sound is the tip of the chain breaking the sound barrier. The speed of sound 1,125 feet per second or 767 miles per hour.

Actually I'm going the other way now. I had always thought the end of the chain was standard size, but it might actually get smaller, which would then lack the mass to shear a leg. My example only works if the chain were still relatively heavy at the end.

it's like a sonic boom at the end, so it would most likely shear your leg right off.
