Hello guys! New here. Grade 11 student. I'm working on a project to investigate how roof angle relative to the horizontal vary with lift, according to Bernoulli's principal. The purpose is to reduce injury in storms. Problems are: Wind blows in all direction and I was thinking about controlling it to horizontal wind but then this might reduce the worthiness of the investigation. I believe that the larger the angle, the lower the lift? So the optimum angle of the lowest lift would just be 89 degrees? I'm thinking of using cardboards to make the house models, but cardboards don't reflect actual house materials? Any suggestions would be greatly appreciated! Thanks in advance!
