In mechanical fits, what is a clearance fit?

• A. Hole is larger than the shaft, allowing movement with clearance
• B. Shaft is larger than the hole
• C. Hole and shaft are the same size
• D. Interference fit requires force to assemble

Answer: (A)

Clearance fit means there is intentional space between the parts so they can move relative to each other after assembly. This happens when the hole is larger than the shaft, creating a gap that allows easy assembly and relative motion (sliding or turning) without forcing the parts together. If the shaft were larger than the hole, it would be an interference fit, requiring force to assemble. If they were the same size, there would be little to no clearance, which isn’t a clearance fit.
