Question

$\text{A hole dimension}30\begin{array}{c}+0.025\\ +0.000\end{array}\text{is assembled}$
$\text{with a shaft of}30\begin{array}{c}-0.009\\ -0.025\end{array}\text{mm.}$
$\text{The type of fit during the assembly is}$

• A. transition
• B. clearance
• C. interference
• D. none

Answer 1

The correct option is B clearance

$\text{Hole- 30}\begin{array}{c}+0.025\\ +0.000\end{array}$

$\text{Shaft- 30}\begin{array}{c}+0.009\\ +0.025\end{array}$

Clearly, hole size greater than shaft size Therefore it is a clearance fit.
