Question

The angle of a component is checked by using a 300 mm sine bar with gage blocks of 42.92 mm height under one end of the sine bar. The dial gage readings at each end of the work piece vary by 0.1 mm, the gage block end being high.
A work piece is 50 mm long and placed on the sine bar at bottom most point. The next height of the gage block tried to get the same dial gage reading at both end of the component, is

• A. 42.32 mm
• B. 41.71 mm
• C. 43.52 mm
• D. 42.82 mm

Answer 1

The correct option is A 42.32 mm

$50mm\to 0.1mm$

$300mm\to \frac{0.1}{50}\times 300=0.6mm$

$h^{\prime }=42.92-0.6=42.32mm$
