SUMMARY
The net force on a flat roof due to wind blowing at 35 m/s over an area of 240 m² is calculated using the equation P = Pat + 1/2 * p * v². Given the atmospheric pressure (Pat) of 100,000 Pa and air density (p) of 1.29 kg/m³, the total pressure (P) results in a net force (Fnet) of 1.9 x 10^5 N when only considering the dynamic pressure. The correct calculation focuses solely on the dynamic pressure component, confirming that the net force is indeed 1.9 x 10^5 N.
