Answer: 7800 lb of force is exerted by an 80 mi/hr wind blowing directly against the front of the garage.
Step-by-step explanation:
Since we have given that
Side of square = 15 ft
Triangular roof is above the square:
So, Base of triangle = 15 ft
Height of roof = 10.6 ft
velocity of wind (v) = 80 miles/ hr
So, Area of square is given by
Similarly,
Area of triangular roof is given by
So, Total area would be 225+79.5=304.5 ft².
And we have to use " ".
So, we will put A = 304.5 ft² .
So, it becomes,
Hence,7800 lb of force is exerted by an 80 mi/hr wind blowing directly against the front of the garage.
