QUESTION: 1

### Which of the following is not a classification of fit?

Solution:

Explanation: Simple classification of fits is down in 3 categories.

QUESTION: 2

### Which of the following always provides a positive clearance between the hole and the shaft over the entire range of tolerances?

Solution:

Explanation: Clearance positive imparts a positive clearance.

QUESTION: 3

### In this case, tolerance zone of hole is entirely below that of the shaft.

Solution:

Explanation: Interference fit provides a positive clearance and hence tolerance zone of hole is below that of shaft.
