its a type of sine bar . it is used in metrology lab .from this equipment we can find tapered angle of a conical spcimen
You can use your trigonometric functions (sine, cosine, and tangent).
They are used to find the angle or side measurement of a right triangle. For example, if 2 sides of a right triangle have known values and an angle has a known measurement, you can find the third side by using sine, cosine or tangent.
Sine (0) = 0 Sin(30) = 0.5 Sin(45) = 0.7071... Sin(60) = 0.8660.... Sin(90) = 1 Are just a few of the Sine(Trigonometric) values.
