A 2-m-long, 0.2-m-diameter cylindrical pine log (density = 513kg/m^3) is suspended by a crane in the horizontal position. The log is subjected to normal winds of 40km/h at 5 degrees celsius and 88kPa. Disregarding the weight of the cable and its drag, determine the angle (theta) the cable will make with the horizontal and the tension of the cable.
