Question:
Tolerances are specified in manufacturing parts:
Tolerances are specified in manufacturing parts:
Show Hint
Tolerance controls fit—not manufacturing error directly.
Updated On: May 22, 2026
- to obtain desired fit
- to allow inexactness of dimensions
- to achieve proper allowances
- none of the above
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Concept:
Tolerance is the permissible variation in dimension.
Step 1: Why tolerance is needed.
Perfect dimensions are impossible in manufacturing.
Step 2: Purpose of tolerance.
To ensure proper fit between mating parts:
• Clearance fit
• Interference fit
• Transition fit
Step 3: Interpretation.
Tolerance ensures functionality and interchangeability. Final Answer: \[ \boxed{\text{To obtain desired fit}} \]
