Question

A shaft and hole are specified as:
$\text{Hole}:35\begin{array}{c}+0.01\\ -0.02\end{array}\text{and}\text{Shaft}:35\begin{array}{c}+0.03\\ +0.025\end{array}$
The size of GO plug gage is

• A. 34.98 mm
• B. 35.03 mm
• C. 35.01 mm
• D. 35.025 mm

Answer 1

The correct option is A 34.98 mm

$\text{Hole}:35\begin{array}{c}+0.01\\ -0.02\end{array}$ $\text{Shaft}:35\begin{array}{c}0.03\\ +0.025\end{array}$

Go plug gage is used for holes

$\therefore$For hole, Go size = Max, material limit

= L.L of hole

= 35- 0.02 mm

= 34.98 mm
