Maybe, but its this term that steel can be considered Non Ferrous. Steel is Iron. Iron is Ferrous, "FE" in the periodic table, from the Roman for iron, Ferrum. Therefore, Steel, being MOSTLY Iron, MUST be Ferrum, Ferrous.... I am taking this to an illogical conclusion, so read with a smile.... I therefore ask how it can be "Non Ferrous Steel" And no this isnt a pedantic dig at the posts above, this is a serious question.... that I am taking as a joke on us all, by Scrap merchants... The term Non Ferrous is used in scrap industry to indicate metals that are not magnetic, even if they are steel. [ source www.answers.com/Q/Is_stainless_steel_a_nonferrous_metal as just for one example there are others out there...] I get that its an alloy of chrome Molybdenum, which I am always trying to pronounce moly-bend-i-um, because I can never get it right, nickel, but, its also 75% IRON.... high carbon content steel is still 99% Iron.... So how can it be NON-Iron, in the statement non-ferrous, which indicates its not iron... Thats like saying a pork pie pastry when the pork is taken away is "Kosher", because the pastry is not pork?.. If you get my drift?... If 75% of an item is something, you cant sort of say its NOT that. This is the type of miss-information in the world that makes it confusing for "sane" people who know the truth... Ma-Lib-Den-Um rhymes with A-Lumen-Um more seriously, scrapyards will cash in stainless steel with non ferrous metals, because stainless sells by the pound and is processed separately from ferritic steel and iron, which all goes together and sells by the ton. so the division would more accurately be metal for steel making, and metal not for steel making. |

 1. What would it take to cause drumsticks to catch fire via normal friction? 2. Is it really possible to affect a pacemaker simply by steady drumming? |

1} Friction in what?. In normal playing, maybe rubbing them together?..
As a drumstick is a wood stick, if you used it with a bow-drill, quite easy to start a fire.
As a Drum stick, well, we used to fly about in wooden planes, and even at the speed of sound, wood doesnt start getting that hot...propellers [wooden ones] routinely spin faster than the speed of sound at their tips, they dont catch fire. [WW2 Spitfire Fighter cited as source for that speedy propeller there...]
As a Human powered "stick", I would like to know what the estimate is of a drumsticks tip speed.
As we have seen wooden or wood based "sabots" used in certain cannons [think chickens...] how fast does a piece of wood have to go before it burns up in the atmosphere?..
Didnt they once fire wooden cannonballs on the show?..
2] depends on how energetic the listeners gets... if they start jigging along to the beat, it could affect the pacemaker trying to keep up?..
Summary.
Both "plausible" in concept, we know space objects burn up in the atmosphere, and they are stones and rocks, so wooden chunks doing meteoric speeds are entirely confirmed as plausible as burning up in earth atmosphere, its just could a Human power that kind of speed.
If your wearing a pacemaker, you are encouraged to keep away from energetic exercise, so dancing to a very energetic beat, not advisable?..

I think you have the angle on the pacemaker, but another option for the drumsticks catching fire is the heat from the impact. if you bang on something then you will warm it up. the question is whether the sticks would shed the heat faster than it could accumulate. |

www.gocomics.com/garfield/2017/04/22"Garfield", 22 April 2017 Garfield decides to prank John by using a dog whistle to summon the local mutts while John's working in the garden. But Garfield grabs his snake whistle by accident, leading to calamity. Now, it's known that snakes can feel vibrations, but can they actually "hear" well enough for a whistle of any sort to summon them?

But Garfield grabs his snake whistle by accident, leading to calamity. Now, it's known that snakes can feel vibrations, but can they actually "hear" well enough for a whistle of any sort to summon them? Nope... thats pure bunkum. The snake charmer uses the motion of the end of his "flute", or whatever it is, thats carved to replicate the head of another snake, to "charm" the snake, the noise is to attract all us dumb 'Umans who are told its the noise.... and believe it. Snakes have the parts for ears, but not the actual hearing ability, as you say, they "Feel" noise, close up. So if a tree falls in a forest and there is no one to hear?.. The snake will feel it. With that much vibration, probably half a mile away as well, but it wont "Hear" it at all... Unless you define the ability to "feel" vibrations of the air around you as hearing.... Which basically is what the definition of hearing is all about anyway, just our ears are super-sensitive to vibration noise?.. However, snake charmer "whistle" is bunkum, that wouldnt happen, the sake would ignore it if it couldn't see or taste the thing. |

As I use to tell my daughter, math is your friend. One cubic foot of helium will provide approximately 0.07 pounds of lift.(or so says Google) One cubic foot is about the size of one extra large party balloon. Doing the math, that would mean you would need about 14 extra large party balloons to lose 1 pound on the scale. Your wrestling team friend better have a very large uniform.

View Attachment"Kevin & Kell", 6 May 2018. Could you compress an entire plunger detonator assembly into something the approximate size and shape of a carrot? consider the size of a modern "dynamo" flashlight. the plunger style detonator was just a portable electric generator. part of the size was to house a generator of that vintage, and part was to make the whole thing more robust. the military uses much smaller ones that are a twist style. and keep in mind, it is only the part above the ground that has to match the carrot. |

This is a catch-all for myths from the funny pages. ** "Henry", 7 November 2015 - View AttachmentThis is a similar premise to the "bird toppling a car" myth from a few years ago. A young boy (say 10 or so) is sitting at one end of a canoe (likely wooden) when birds begin to sit in the other end. In time, the weight of the birds is enough to lift the boy's half of the canoe out of the water. From what I know of canoe... open or closed, canoe or kayak?. if its an open one, the weight of the birds will push their end under water before the kid gets raised out the water. And then you sink. If its a closed over one, and the kid is in the back seat of a two man canoe, again, the bird end is going under water, birds dont want to get wet, fly away, and up pops the canoe again, before the kid gets lifted out of the water?. If its an open one, if the kid is "That far back", he risks putting his own end below water on his own, plus weight of birds to counter that extreme weight unbalance, thats a lot of weight, canoe will liable sink before the kid gets lifted that much?. And if the moment of rotation is about half way with a LOT of weight, say the kid is no lightweight, he had his share of pies, enough with this PC crap, he is a fat kid, then the weight on one end will snap the bloody thing in two. Fibreglass aint that tough... Try this, anchor a canoe to the ground one end, put a log under it half way, and try standing on te other end, see how long it takes for someone to tell you "your goina' wreck it is ya do dat?.." Heavier build wooden, maybe, so the build of the canoe is a factor, the strength of the materials, the weight of the kid, and the number of birds you can usefully fit on one end of what only can be described as a bank stabbing javelin in shape, sharp ended thing with not a lot of room at the bows or stern. Would there even be enough room on one end of a canoe to settle that many birds anyway?. unless its a heavy bird like Emu, that dont fly, or Albatross, and you have a lot of them, the bird per square inch per Lb is going to mean a lot of bird... is there enough space?. |

Appologies, for some reason, my browser took me right to the start of the thread, and I missed the date of that post before I replied [where are my bloody glasses?...] yeah, it got discussed, I missed that didnt i?> however, it occurred to me we didn't do the math on the problem. given the dynamics of bouyancy and displacement, and assuming your boat doesn't swamp or break in two, the boat will behave predictably under load. if the load is imbalanced in the boat, the boat will rotate under the load until the center of bouyancy is under the center of mass. something like a rocking chair or rocking horse and unlike a seesaw in which the fulcrum is fixed in place. theoretically, at this point, the hull section directly under the center of mass would be parallel to the water - though that assumes a boat that is a uniform arc section with both ends clear of the water, and the lengthwise profile of a canoe is not. however, assuming that, if there is a person in one end, and a weight twice that of the person equidistant from the center in the opposite end, that would place the center of mass midway between the center and the weight. in a test universe, that would mean the person was three times the distance from the center of bouyancy as the weight, and for every inch the weight pushed the boat down, the person would be lifted three inches. |

I would think that with a fan with a metal blade you could slowly shave away the peel on a potato. It would probably take a lot longer than just using a manual potato peeler or just a knife. |
