Metrology: Hole and Shaft Limit Fits

Metrology: Hole and Shaft Limit Fits

Original quantitative topic practice in English. All 24 questions are included in a shuffled order. Each question supplies its own data and model assumptions; use only those assumptions. Choose one answer. Practice target: 20/24, not an official examination pass mark. Keep full intermediate precision. These exercises cover the calculation scope in the title; they do not constitute a full Red Seal examination, trade qualification, site design or operating specification.

A drawing specifies a hole from 25 to 25.04 mm and a shaft from 24.98 to 25.02 mm; limits are inclusive. Define clearance as hole diameter minus shaft diameter. A negative result means interference. Determine worst-case dimensional results only; do not infer suitability for a real assembly. Calculate the clearance between midpoint dimensions in mm. Keep intermediate values unrounded; round the final answer to 4 decimal places if needed.
