1. The problem statement, all variables and given/known data Explain if wind on walls and roofs of buildings is considered a pressure or a force? 2. Relevant equations P = F/A 3. The attempt at a solution Wind load should be measured in terms of pressure?..but I don't know the exact reason why it is. Does it have something to do with "non-contact" force?.. Thanks for your time for the explaination!
