It depends on the intensity of the tornado and the size of the plane. As an example, depending on the design, a Boeing-737 weighs about 30 to 50 tons empty and about 55 to 95 tons fully loaded. Based on records of large objects being moved, a strong enough tornado, almost certainly an EF5, could lift a plane at the lower end of this range. Smaller airliners could probably be lifted in that case as well.
A violent tornado, however, would place an enormous amount of shearing stress on a plane, something planes are generally not designed to withstand. So, a commercial airplane struck by such a strong tornado would likely be torn apart rather than lifted as a whole.
The strongest can pick up anything from buses, cars, small buildings, houses, and even trains! In the late 1800s, there was a record of a thin EF5 tornado and charging at a train in Minnesota. The tornado was recorded to lift up the 60-tonne train 30 meters high in the sky and throwing it 80 ft away into a ditch.
It depends on the intensity of tor tornado. The heaviest objects known to have been lifted by a tornado was a 90 ton oil tank. The intensity of the tornado that did this was likely well into the F5 range.
Very often, yes, a tornado will lift objects into the air. Light objects such as pieces of paper can make it all the way into the stratosphere.
Air travels upwards rapidly in a tornado. If the speed of the updraft exceeds the terminal velocity of a person, then it can lift people off the ground.
In addition to rotating, air in a tornado flows upward fairly rapidly. Often, this is enough to lift objects of the ground, sometimes very large objects.
Yes, it can.
Yes. Tornadoes have been known to lift up airplanes.
If the tornado is strong enough, yes. It would normally take at least an EF2 tornado to lift a truck.
lift
Lift pushes the airplane up. The way air moves around the wings gives the airplane lift. The shape of the wings helps with lift, too.
Lift
Lift acts against the force of gravity, pushing the aircraft up.
No. An EF1 tornado can lift a poorly secured roof, but not much more than that.
An EF0 tornado can't pick up much of anything, so probably not.
Lift keeps an aircraft up, thrust pushes it forward.
I am going to assume that aeroplane=airplane when I answer this. An airplane stays in the air by generating lift on its wings. As long as an airplane can generate sufficent lift it can stay in the air. However once the lift being generated falls below what is required for the plane to stay up... uh oh.
Yes, a strong enough tornado could lift a tractor trailer. It would probably take a a strong EF2 or EF3 to do so.
