Is the weight of a truck full of chickens less if the chickens are flying?

If the truck and the birds are the same, they will weigh the same no matter what the birds are doing inside. It seems that when in flight, the birds are not touching anything, so they cannot contribute any weight. But the key is that birds do not magically become weightless by flapping their wings.

Does a truck with birds in it weight more when the birds are flying or when they are all standing on the bottom of the truck?

No. A flying bird pushes air down, and this air pushes down on the truck, with the same force as the bird’s weight. The only way the birds would not contribute to the weight of the truck is if they were in free fall.

Do flying birds in a truck change the weight?

They concluded that the contents being in flight made no difference to the weight, and theorised that the downdraft of air from the wings or rotors pressed down against the base of the box with the same force as the resting bird or helicopter.

Do birds weigh less when they fly?

Weighing a bird on the wing isn’t easy, says Lentink. As it flaps its wings, it pushes on the air both above and below, meaning its effective weight changes. On the downstroke, though, the birds push on the surrounding air so forcefully that they generate a vertical force of up to twice their body weight.

Who was the driver of the Chicken Truck in Melbourne?

The Porsche driver has since been identified as mortgage broker Richard Pusey, 41, from Frankston. He survived the crash, allegedly took video of the scene – which surfaced on social media – and fled on foot, police claimed.

Is it true that birds fly in a truck?

It’s an urban myth that had US TV show Mythbusters weighing a truck full of pigeons on a scale and getting them to fly. Now it seems there’s some truth to the idea that a truck driver carrying a cargo of birds can lighten the load by making the birds fly.

Why do birds flap at different times in a truck?

In reality, the birds will tend to flap at different times, meaning the cargo will, on average, maintain a stable weight. The result isn’t entirely surprising. “When you look at the downstroke muscle it’s much bigger than the upstroke muscle so it makes sense that the downstroke is doing more,” says Lentink.
