Virtual Angle Measurement, simulator of goniometer in degree resolution five minutes (5')

Goniometer How to use Angle Measurement Equipment, goniometer dopted with vernier for erading in degrees (°) and minute (')

The Angle Measurement is an instrument of mobile pieces where you can mark or measure angles. On this simulator, the diameter from the named 'graduated disc' is divided in 360 equidistant spaces, named 'degrees', that are the 360 circular sectors of 1° (one degree) each.

Turning the vernier you will see the angle formed with one fixed line. The 'zero' mark (0) of the vernier mark the iteger degrees of the angle. The vernier has twelve divisions that refers to the sixty minutes (degree division) that means that each mark 'mark'5' (five minutes). The interpretation of the vernier can be comprehended in the page: 'vernier: simulator of reading and interpretation: vernier scale in millimeter, tenth resolution - Metrology'.

Observe that in ths virtual Angle Measurement the named ' direct vernier ' (the N graduations of teh vernier correspond to N-1 graduations of the mais scale). This way, we must 'read' the marks following the same principle used in the vernier of the caliper, for example.

The mechanic of utilization of the simulator of goniometer of the end of the page is: turn (drag and drop) the vernier and investigate the reading of the degrees and of the minutes. One small icon, similar to an instrument of marks in metrology, (left of the screen) will help to see the angle formation.

Because of the limitations of the monitor resolution, some of the marks can appear not aligned.
