The height (in mm) for a 125 mm sine bar to 'measure a taper

The height (in mm) for a 125 mm sine bar to 'measure a taper of 27'32' on a flat work piece is _________(correct to three decimal places).

θ = 27°32' = 27 +		32		^°	= 27.533°
		60

In sine bar, sin θ =	H
	L

sin 27.533° =	H
	125

H = 57.782427
H ≈ 57.782 mm
