Question

$\text{A shaft is specified by}50\begin{array}{c}+0.005\\ +0.015\end{array}\text{mm and hole is specified by}50\begin{array}{c}+0.01\\ +0.000\end{array}\text{mm.}$
$\text{The maximum clearance between hole and shaft is}$

• A. 0.005
• B. None
• C. 0.01
• D. 0.025

Answer 1

The correct option is D 0.025

$\text{Shaft}=50\begin{array}{c}-0.005\\ -0.015\end{array}mm$

$\text{Hole}=50\begin{array}{c}+0.01\\ 0.00\end{array}mm$

Max clearance = U.L of hole - L.L of shaft

= 50.01 - 49.985

= 0.025 mm
