shaft is one ________ .
whose
upper deviation is zero
whose
lower deviation is zero
whose
lower as well as upper deviations are zero
does
not exist
whose
upper deviation is zero
Basic
shaft is one whose upper deviation is zero i.e. shaft is kept as constant
member. This is known as shaft basis system in which only whole size varies.
Hence,
