Why do we use solid shafts for transfer of power in case of
pumps/ turbines & other machines why we use a hollow shaft
(pipe) in universal joints of automobiles; although the
rated load and twist is approx. the same?

Answer Posted / shakeb azim

Because rpm of pumps & turbines is too high & at that speed
hollow shaft posses & face more torsional force, so it will
bend. That's why we use solid shaft insted of hollow shafts.
