[Request] How much weight is that truck carrying
I'm making a bunch of assumptions, so the end result may be off. Please give me corrections! I would love to know more about this stuff.
Let's start by assuming we can see the end of the truck. This distance is approximately 200 meters.
In a meter of road, there are about 6*9=54 flags.
After multiplying the numbers, we get that the truck has about 200*54=10800 flags.
Now, I think a single flag can weigh from 1kg to 2 kg (correct me if I'm wrong! This is different from country to country and I don't live in America), so the total weight comes down to ~15 tons, or ~33000 pounds.
The primary weight you'd have to calculate is more the trailers than the flags. An unloaded 53 foot (16.15m) trailer weighs about 10k pounds. If we take your number of 200m (though I agree with other comments that it looks longer than that) then you'd need 13 of these trailers, which would alone weigh 130k lbs.
This would bring your new total weight to ~163,000 pounds.
That is way longer than 200 meters.
Does 500 m make sense?
Makes more sense, yeah, but i'd eyeball it at not more than that, prob bit less. Theres a decent curve and also perspective issue. I know you can calculate perspective angle to correct for distance but its beyond my paygrade.
I was thinking the same thing. The photo is about 30° angled down, and you can estimate the size of and compare the width of the front and back to determine distance, + ~20% for accounting for curviture. I just don't know the equasion for that
