339,000 lbs
The question should be: how do you weight a 747 without a scale of any sort?
(Answer later.)
Measure the area of each tire that is in contact with the ground. Sum these values.
Measure the air pressure in each tire. Sum these values.
Tot. Pressure (lbs/sq in.) X Tot. Area (sq. in.) = how much a 747 weighs.
I am impressed but the air in the tires is already under some pressure so don’t you need to calculate the difference in pressure between a tire that is not under any pressure with one that is under a 747? This difference dP*A = weight
i thought airplanes had tubeless tires.
my take on it:
utter a random value, asked if it is greater than what uttered, some people / baggage was added to it
and if less, they were removed..
corny, but gives the answer
If we are supposed to a weigh Boeing 747 without using a scale, i would put the aircraft in a ship in the water…. rather ocean or sea…. Dur to the weight of 747, the water level in the sea would increase. Now remove the aircraft. You can see the difference of water level in the sea (Although its minimal in a large ocean)…. we can derive the approximate weight of the boieng 747 bu multiplying the density of waterinto the amount of differnce between the water levels.
Another option that we can use is…. mark the increase in water level when the ship is loaded with 747. After removing it, again fill the ship with large stones or some material of a known weight… Keep on filling it until it reaches the marked the increase of water level. The amount of weight at that moment of time on the ship is equivalent to the weight of 747 aircraft.
Hope this works…!!!
350000 pounds
Question was: how do you weight a 747 without a scale of any sort?
I would use ‘google’ to know the weight, it would be the fastest and why need a scale? (Boing’s web or other technical sites surely has it).
Now, again you may ask, how do I weight my own plane (different model maybe) without a scale?
I would read the manual or ask the builders :).
(362,880 to 396,900)kg
I think the question asked is , “How much does a 747 weigh?” . AND NOT the “methodology to weight a 747″.
as Kaisar aptly puts it , ask Google. but that’s surely gonna piss M$ ppl off , if u know what i mean
Hey guys, the answer is obviously 42.
It again depends on how you interpret 747. They didn’t ask how much does BOEING 747 weigh, did they? 747 grams of water will of course weigh 747 grams. Howzzat!
regardless of the weight, the interviewer is watching how you will approach the problem, you can tackle from different angels, and you have to explore what you will do and explain it to the interviewer.
For example, you can say, a compact car weight is about 3400 lb, see how many of these you can fit in a boeing, if a boeing has 50 rows, each 3 rows are about the same length of a car, so divide 50 rows / 3 —> total number of cars to fit in an airoplane is about 17 cars long, now, the width can fit about 4 cars toos. so total cars will be around 70. mulitply 70X3400 –> 238,000 (~~ 238 tons). now add to that the the body tires, engines, etc.. assume another 100 tons, you get total of 338 tons..
so it’s how you think about it, regardless of the number you will end up with..if you are logial, you will not be too way off.
It depends on the 747 particles’ distribution in a gravitational field. Also, if the plane is flying at a realistic, steady height, the upthrust=downwards force due to gravity, therefore there is no overall force, so it is weightless. Assuming they meant the mass of a Boeing 747, I would find a known amount of litres of water (since it says on the bottle)
and put them on a giant set of scales with the 747 on the other side and see when they balanced. Since 1 litre is approx. 1 KG, I would have a good answer. Or I could say I don’t know, which is entirely correct at this moment.
I’m sure the weight can be derived by some function of ground speed required to take off and engine force. Unfortunately I’m not an Aeronautical Engineer…
It is a tarp. The interviewer is trying to watch the approach of the candidate towards the problem. First of all think why to weigh 747? Why not 858?
I think it is boeing 747. Which I cant weight.
1. The 747-400 wing weighs 95,000 pounds (43,090 kg).
2. Empty Weight 61,864 lb (28,120 kg)
3. Maximum take-off weight 108,218 lb
(49,190 kg)
4. Maximum landing weight 99,000 lb
(44,906 kg)
Done………..
Well……when it is in the air it does not weigh anything. Now if the question was what is the mass of the aircraft……..
Why are you all assuming we are on earth, the plane would undoubtably be a different weight on the moon.
747 units.
Call Boeing and tell them the N-number of the 747 to be weighed. The N-number is the unique number assigned to each plane and it’s usually painted on the tail. Boeing can tell you every detail about that plane.
