Radius Guage
to calculate the diameter or radius of a circle from a partially rolled metal. I would make an adapter to mount on the dial indicator to a known distance to represent the chord of a circle (in my .pdf would be 4") and using the measured distance (0.2190) and end result will calculate the diameter in this case to be 18.4838. I can use autocad and draw up each time, but I would like to write a VB app to speed things up. I can write the program, but I need help in the background trig needed for these calculations.

Here's a section from Machinery's Handbook which deals with mathematics. There is a section called "Segments of Circles" on page 80 which should tell you what you need to know. Page 86 has a table of formulas for "Solution of Triangles" which might also help...

Got it. I have attached it if anyone wants to use it. It should help to keep the waste minimal when rolling out circles or part circles.
