A steel shaft (7,850 kg/m3) with a diameter of 3.0 cm and a
length of 40 cm falls under its own weight into a vertical tube
with an internal diameter of 3.02 cm. The clearance that is assumed
to be uniform is filled with a fluid whose viscosity is 0.45 Ns/m2.
Determine the terminal velocity of the steel shaft.
