Q: Limits & fits: unilateral system of tolerance — where is the tolerance placed? Interpret the definition of unilateral tolerance relative to the nominal size. Choose the correct option.

Concept In a unilateral tolerance system, all permissible variation lies on one side of the nominal (basic) size (e.g., +0 / −0.010 or +0.010 / −0). Final Answer On one side of the nominal size

Difficulty: Easy

On one side of the actual size
On one side of the nominal size
On both sides of the actual size
