Question
Transcribed Image Text:A 90 kg man stands in a very strong wind moving
at 14 m/s at torso height. As you know, he will
need to lean in to the wind, and we can model the
situation to see why. Assume that the man has a
mass of 90 kg, with a center of gravity 1.0 m
above the ground. The action of the wind on his
torso, which we approximate as a cylinder 50 cm
wide and 90 cm long centered 1.2 m above the
ground, produces a force that tries to tip him over
backward. (Drag coefficient for the cylinder in this
position is Cp 1.1.) To keep from falling over, he
must lean forward.
What is the magnitude of the torque provided by the wind force? Take the pivot point at his feet Assume that he is standing
vertically. Assume that the air is at standard temperature and pressure
Express your answer with the appropriate units.
