Question B2 A smooth cylindrical pole of diameter d-200 mm and height H-30 m has been erected vertically in sandy soil. It is kept in position using a rope, as shown in Fig. B2. It is assumed that the sandy soill cannot support any moment about the centre of the soil ball, denoted point O. Air (density p-1.23 kg/m³ and viscosity μ-1.79x105 N.s/m²) flows past the cylindrical pole at a speed of V-72 km/h. The drag force on the rope can be neglected. Determine the tension in the rope. d = 200 mm V = 72 km/h 45° Figure B2 h = 20 m w (E = H Total for question: 25 marks
