Captain America vs Batman(no shield-no gadgets)

Such pipes have a tensile strength of 400MPa. This is 400 million netwons per square meter. Assuming the thickness was about 1cm, then from a thin square rod we would get a cross sectional area of (1cm)^2 or (1/10000)m^2 . Multipying this area by the tensile strength and converting to tons yields 4.5 tons.
That means a rod with twice the area would yield about 9 tons. The pipe was circular and thus had more than twice the cross sectional area as 1 rod.

400 MPa is a little high but yep that basic steel design right there. same reason a little steel cable can tow a vehicle much heavier...it takes much more force to break it than it actually weighs

That's a lot of unsubstantiated numbers there. Thanks I guess? What I tell you is that one summer I had a job laying down asphalt on flat top roofs with pipes like that, and I've moved old pipes like that around. Two people can do it, they don't weigh that much. You certainly can't hang a f@cking car off it, let a lone a 7-8 ton truck. Christ.

The weight of the pipe has nothing to do with its ability to support a load...a diamond is light, care to break it with your hands?

And before you start Job dropping i'm a Structural Engineer....you do the carrying, I do the designing.

h1a8 I think you are overestimating the cross section area of the pipe, but still, and human ripping it in that manner is an incredible feat

Those types of rooftop pipes aren't meant to support loads... and aren't attached to roofs in any sort of manner to facility such a function. If a person tied a bungee to the thing and then jumped of the roof... they'd probably pull the damn thing down with them. Never mind hanging a truck form the thing.

I can break a diamond with a hammer. 😉

You are going to give me shit for a summer job I had in high school? 🙁

I'm an illustrator and graphic artist now, so I design too... I just make far less money then you. On the plus side I don't need to use math, get up before noon or wear pants, so it does have its benefits. Hehe

I'm not a graphic designer i'm an engineer, although I do like to do graphic arts as a hobby.

But look at the scans, yes they are not structural elements and not secured to the roof to withstand huge loads but it doesn't show Batman lifting it off the roof, it shows him RIPPING THE PIPE IN PIECES. realistically the pipe would have come dislodged from the roof before being torn in tension, that's bad writing/art but since thats what they show him doing, ripping it in tension, THAT is the feat.

And I know you were joking but force of a hammer strike > greater than the weight of a diamond.

Cool.

I don't know man those old cast iron pipes can get pretty week in spots, some times the rust rots right through the damn thing.

I heard he was diseased or something.

This is one of the most asinine things I have ever read.

Captain America and the car are two separate entities. Captain America is not attached to the car, which means if he isn't physically capable of pulling down the helicopter of his own volition... then the mere act of trying and failing against the resistance of the helicopter pulls him clean out of the back seat of that car. Bracing his foot against the back seat doesn't weld him to the car, it merely affords him a better footing and more uses of the stronger muscles of the legs and lower back.

If Cap was on a skateboard then would he be able to pull the helicopter down? Clearly no.

But if the skateboard somehow push against the ground to prevent the helicopter from pulling the skateboard then Cap would be able to pull the helicopter down, provided he doesn't slide off the skateboard.

You see the skateboard has to apply a force against the helicopter or the helicopter would pull it as well. The car is providing a force against the helicopter otherwise the helicopter would pull it away.

You are not understanding basic physics Srank. Someone please help me out here.

ctsketch?

you should be asking why cap wasn't simply pulled up by the copter. the car isn't part of his lower body

Seriously. I don't know how else to explain it to him. 🙁

This is the most stupid logic I have ever read on a site. If he were on a skateboard and a helicopter were pulling him, he would be pulled off the skateboard... unless he somehow had the muscle fortitude to keep himself on (which is inhuman).

not diseased, suffering from the deterioration of the ss serum in his body. he was a mess for a while til he finally worked it all out and defeated crossbones.

The vehicle Captain America is on / in is completely irrelevant. One end of the grappling hook is tether to the helicpoter. The other end is tether to an object in Captain America's hand. If at any point that line goes taunt, and Captain America isn't physically strong enough to pull the helicopter against it's resistance... then Captain America gets yanked up off the ground by the helicopter. It doesn't mater if he is on a car, a boat, a skateboard, roller blades, or chilling in on the patio in a lawn chair. You'd be right if the line was fixed to the car, or Captain America was buckled in with a seat belt, but neither of those things are true.

as for the chopper--he was braced against the car. let's assume the car DID aid him. in order to do so he would have had to have the leg strength still to maintain his braced stance against the pull of the chopper anyway as he was not fastened to the car. since he was independent of it, the chopper would have pulled him free first before pulling the car.

put yourself in the car--think you or anyone you know could have done it? clearly it was a superhuman feat.
