A basic shaft is one whose
Discuss
Answer & Solution
Answer: Option B
Solution:
A basic shaft is one whose Upper deviation is zero.
Upper Deviation: It is the algebraic difference between the maximum size and the basic size. The upper deviation of a hole is represented by a symbol ES and of a shaft, it is represented by ES.
Lower Deviation: It is the algebraic difference between the minimum size and the basic size.
