In order to conduct insulation treatment, the wire is pulled through the middle of the mold filled with insulation coating. The diameter of the wire is known to be 0.8 mm and the viscosity of the coating mu equals 0.02 Pa smu equals 0.02 Pa smu equals 0.02 Pa s mu equals 0.02 Pa s, the diameter of the mold is 0.9 mm and the length is 20 mm, and the pulling speed of the wire is 50 m/s. Try to calculate the required pulling force.
