What damage can an F1 tornado do?
An F1 tornado can break windows, strip the surface from a roof and heavily damage a mobile home. Barns will likely be destroyed. Poorly secured roofs may be torn off.
How fast would winds be moving in a tornado tore roofs off buildings?
It depends on how well attached the roof is, but it would usually take winds of at least 120 mph (193km/h) to remove the roof of a building. This is in the range of an EF2 tornado.
What is the strongest strength of a tornado and the least strongest strength of a tornado?
The highest strength rating a tornado can receive is EF5. Areas impacted by the full force of an EF5 tornado will experience total destruction. Well-built houses will be wiped clean of their foundations, and steel reinforced structures will be leveled. The lowest strength rating a tornado can receive is EF0. An EF0 tornado can peel shingles from roofs, break tree branches, and knock down a few trees. Some very weak structures may be destroyed.
What does an F1 tornado do?
F1 damage is generally describes as moderate. Typical F1 damage includes broken windows, severely stripped roofs, badly damaged or mostly destroyed trailers, and collapsed garages and porches.
What can a tornado lift?
It depends on the strength of the tornado. Weak tornadoes will lift up light objects such as small tree branches. Strong tornadoes have been known to lift up cars, trees, roofs, barns, and sometimes people and animals. Violent tornadoes have been known to lift up and throw heavy construction equipment, well constructed houses, and sometimes larger structures.
How do tornadoes lift roofs off building using Bernoulli's principle?
The wind of the tornado creates and upward pressure gradient against the roof that works to essentially peel it off.
How roofs are lifted off buildings in tornadoes using Bernoulli's principle?
As the winds of a tornado move quickly over the roof, they create low dynamic pressure on top of the roof, causing it to lift.
How bad an is EF2 tornado?
An EF2 tornado is fairly bad. Such a tornado can tear the roofs from most houses and destroy mobile homes.
What is the prepotitional phrase in The tornado uprooted trees and roofs of houses were blown away?
The prepositional phrase is "roofs of houses."
what- The tornado uprooted trees and roofs of houses were blown away?
of houses
How does it look after a tornado?
It depends on how bad the tornado was. A relatively weak tornado will topple trees and power lines, damage roofs, and destroy some weaker structures. After an intense tornado many homes may be destroyed or be without their roofs. Debris is scattered everywhere. After a large, violent tornado neighborhoods may be turned into fields of debris with trees stripped of their leaves and bark.
Why do roofs blow off during a tornado?
There are a few mechanisms. First, the wind going over the upward-pointing roof creates and upward force owing to Bernoulli's principle. The wind may also catch the roof under the eaves or cause a gable to fall inward and pick up the roof from below.
What damage can an F1 tornado do?
An F1 tornado can break windows, strip the surface from a roof and heavily damage a mobile home. Barns will likely be destroyed. Poorly secured roofs may be torn off.
How big is an F2 tornado?
An F2 tornado does not have any particular size. That is not how the scale works; it rates tornadoes based on damage. An F2 tornado (EF2 as of February 2007) is a tornado that tears roofs from well-built homes, derails trains, and destroys trailers. Winds in an EF2 are estimated at 111 to 135 mph.
What is an F-3 tornado like?
An F3 tornado is pretty destructive. In the areas hit hardest well built houses will have their roofs removed and multiple, possibly most walls collapsed. Weaker structures will be completely destroyed. In such a tornado cars are tossed an trains derailed.
What damage is likely to occur with an F1 tornado?
Typical F1 tornado damage surfaces peeled from roofs, windows broken, garages and porches collapsed, trailers overturned or severely damage, and trees knocked down.
What destruction can a tornado cause?
Damage could range anywhere from minor damage to roofs and siding to the complete obliteration of well-constructed buildings
