Question

$\text{A hole is specified by}30\begin{array}{c}+0.008\\ -0.0005\end{array}\text{mm}$
$\text{and shaft is specified by}30\begin{array}{c}+0.007\\ -0.004\end{array}\text{mm}\text{.}$
$\text{The type of fit and allowance for the fit is}$

• A. Interference fit and 0.007
• B. Transition fit and 0.007
• C. Clearance fit and 0.007
• D. Transition fit and 0.012

Answer 1

The correct option is D Transition fit and 0.012

$\text{Allowance =minimum clearance or maximum interference}$

$=\text{U.L of shaft -L.L of hole}$

$=30.007-29.995=0.012$
