1. Air flows over a 60 f t high circular smoke stack at a uniform speed of 30 mph. Find the total force acting on the stack if its diameter is 6ft and the air temperature is 70°F. 2. A 0.5 in. diameter cable is strung between poles 120 f t apart. A 60 mph wind is blowing at right angles to the cable. Find the force acting on the cable due to the wind. The air temperature is 40°F.
