During the measurement of internal taper of a part using standard balls of diameter $$15$$ $$mm$$ and $$20$$ $$mm$$, the large ball is found to protrude by $$5$$ $$mm$$ $$\left( {{h_1}} \right)$$ and the top of small ball is found to be $$35$$ $$mm$$ $$\left( {{h_2}} \right)$$ below the top face of the gauge. The taper angle, in degree, is ________________.

The alignment test ''Spindle square with base plate'' is applied to the radial drilling machine. A dial indicator is fixed to the cylindrical spindle and the spindle is rotated to make the indicator touch the base plate at different points. The test inspects whether the
A
Spindle vertical feed axis is perpendicular to the base plate
B
Axis of symmetry of the cylindrical spindle is perpendicular to the base plate.
C
Axis of symmetry, the rotational axis and the vertical feed axis of the spindle are all coincident
D
Spindle rotational axis is perpendicular to the base plate.
