Richiee Posted February 8, 2011 Posted February 8, 2011 a wind blows at 25 m/s over your house, what is the net force on the roof if its area is 250 m^2? help would be much appreciated
SMF Posted February 8, 2011 Posted February 8, 2011 This could vary between a large negative and a large positive net force depending upon the shape of the roof relative to the wind direction. SM
