Question

What would happen if high-speed winds blew over the roofs of buildings?

Answer 1

• If the roofs were weak, they could be lifted and blown away.
• This happens when high speed winds are blowing above the roof of a building, air pressure above the roof gets reduced.
• The air pressure inside the building is much more than the air pressure above the roof.
• This difference in the air pressure makes the roof blown away.
• Like in the figure above ,P1 is the pressure created by blowing winds which is less than the pressure P2. Thus, it could result in upliftment of the roof.
