Question

$\text{In an interchangeable assembly,}$
$\text{shafts of size}25\begin{array}{c}+0.04\\ +0.02\end{array}mm\text{mate with holes of size}25\begin{array}{c}+0.03\\ +0.02\end{array}mm.$

$\text{The maximum material limit of hole and minimum material limit of shaft are, respectively}$

• A. 25.03 mm, 25.04 mm
• B. 25.02 mm, 25.02 mm
• C. 25.03 mm, 25.02 mm
• D. 25.02 mm, 25.04 mm

Answer 1

The correct option is B 25.02 mm, 25.02 mm

As we know,
Maximum material limit of hole = lower limit of hole

$\therefore \text{Maximum material limit of hole = 25.02 mm}$

Minimum material limit of shaft = lower limit of shaft.

$\therefore \text{Maximum material limit of shaft = 25.02 mm}$
