Question
Why do huge hoardings have holes in them?
Answer: Option B
:
B
In windy conditions, the air pressure difference over the two faces of a hoarding can create a massive force. This force can easily topple or destroy the huge hoardings. Holes in the material allows the wind to pass through which greatly reduces the overall pressure difference on the structure.
