Dangers of Bernoulli’s effect
? Blowing of roof tops- when a fast moving air passes above a roof top, the air pressure above the roof will be higher than that below it. Thus the resultant upwards force acting on the roof may blow it off if it is large enough.
? Car accidents- when a small car and a large truck both travelling at high speeds and in opposite
directions overtake each other, the small car is likely to be dragged onto the truck. The speed of air
between the car and the truck is very high and hence a low pressure exists between them. The resultant
inward force acting them draws them closer together. The car being lighter has a higher chance of being
dragged onto the truck, causing an accident.
