asides from the fact its a great movie (with a true bad ass baddie) , is it possible to blow a lock/barrel clean from a door with a pressurised air cylinder without needing the arm strength of Chuck Norris to hold the device in place?

Seems implausable to me.

I presume the device has a bolt which fires outward upon release of air pressure? but it would still need holding firmly in place or it would simply kick back, right?

It’s a captive bolt – like those used to slaughter livestock during foot and mouth.

It’s the same principle as firing a bullet from a gun. The bolt is small and light compared to the gun/hand/arm/body of the individual holding it so there is some recoil, but nothing that a normal person can’t deal with.

The person dealing the death/lock damage isn’t using their strength to break the lock, they’re merely providing inertia against the force pushing the bolt out.

I struggle to understand how the captive bolt could break the lock free from its mount and clean across the room without considereable recoil as it strikes the surface of the lock?

On a similar vein, can Superman really fly? 😉

DS – what doubts are you trying to raise about Superman?

Nothing at all, he can clearly fly, my mistake. Sorry. 😳

Just watching it myself, and was thinking this, as I do every time I watch it. All depends on the mass and velocity, as that lock thing looked pretty heavy when he picked it up and when it hit Moss, and it was obviously travelling pretty fast, but no where near fast enough to kill him, so as it might have the same mass as a huge calibre bullet, but no where near the velocity, would have a recoil somewhere between a small pistol and an assault rifle, at a guess.

I’ve never seen superman take off from a conveyor belt, which brings into question whether aircraft real can.

Its a physics thing. Small mass, high velocity, limited recoil.

so its confirmed. an air cannister/cylinder can produce enough PSI to shear the metal barrel/lock, without any real sign of recoil.

I love physics me.

They store up plenty of energy, you’ll be in trouble if it all comes out at once.

This cylinder took off someones hand and some large chunks out of the brickwork:

owowowowowow!

did he get any of his hand back?

that film would be so much better with a happy ending
