Wind blowing off a roof physics.

Physics stack exchange is a question and answer site for active researchers academics and students of physics. 20 when wind blows at high velocity roof tops are blown off because pressure a outside is more than inside the roof b inside is more than outside the roof c increase due to wind velocity d is exerted by air from outside. Assume the roof is not nailed down. The air pressure above the surface is lower compared to that underneath.

The high wind blowing over the roof creates a low pressure in accordance with bernoulli s principle. If the house is 6 2 m x 12 4 m in size estimate the weight of the roof. If the strong wind blows all day. This cause the roof to blow off.

Physics q a library ii a 180km h wind blowing over the flat roof of a house causes the roof to lift off the house. Ii a 180 km h wind blowing over the flat roof of a house causes the roof to lift off the house. The aeroplane work in the same principle lower pressure on top surface. Physics fluid flow 1 of 7 bernoulli s equation.

How strong winds from tornadoes and hurricanes can lift off roofs with overhangs. But at the corners and at the edges of the roof typically by the very nature of the wind blowing across the roof it exerts a higher pressure depending on the way the wind blows the shape of the roof and the location on the roof there will be negative pressure suction or positive pressure pushing like when the wind slaps your. If the house is 6 2 m x12 4 m in size estimate the weight of the roof. Michel van biezen 162 335 views.

This difference of pressure causes an upward thrust and the roof is lifted up. A loose shingle can also allow water or wind to get caught under it which can lead to the shingle blowing off. Assume the roof is not nailed down. In maine exposure to high winds and the harsh winters can all work against the longevity of your shingles.

High winds are one of the most common causes of shingles blowing off during a storm.
