Answer is:
wires in two adjacent strands are twisted in opposite direction
Answer is:
diameter of bolt
Answer is:
whose upper deviation is zero
Explanation:
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.
Answer is:
whose lower deviation is zero
Explanation:
A basic hole is one whose Lower 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.
