How does a ship attends its axial motion?
via the perpellas on the bottom of the ship
Is a ball and socket joint a uniaxial joint because motion is limited to rotation in a single plane?
what do you mean? axial compressor (or) axial turbine? Their missions are different. Design for axial compressor or turbine, must be consider their performance. The performance is characterized by - pressure ratio, rotational speed and efficiency. The details of how to design axial fan, are very complex.
