Given an arc or segment with known width and height: The formula for the radius is: where: W is the length of the chord defining the base of the arc H is the height measured at the midpoint of the arc's base. They are used to measure existing radii, which is a critical operation when it comes to applications such as pattern making, precision machining, layout creation, and part inspection. To draw a circle you need to know its radius. The lines start where the cover begins to curve, and ends where they cross. We can now use the CAD program to measure the depth to the point where the tool contacts the curve. Your hot tub cover will be too large. Measure the rim width (W) and divide by two. In other words an accuracy of +/- 0.03 about a nominal displacement of 5 mm gives us a radius range of 1.7 mm. The smaller the increment, the more accurate (and smooth) the arc line will be. Use a carpenters square. It works for arcs that are up to a semicircle, so the height you enter must be less than half … Use a ruler to measure diameter if you don’t have a bolt gauge. An atom will have different radii depending on the bond it forms; so there is no fixed radius of an atom. Now you can measure the cord length in reference to the height of the square heads to figure the radius. The customer was not careful to measure the true arc of the bend, and thus, estimated a much larger circle. Check this measurement by performing the procedure in reverse (see Diagram 2 — now place your ruler against the horizontal edge, parallel with the horizontal red line), taking the alternate radius measurement (the radius at right angles to that which you have just determined). As you can see from the diagrams, the same atom could be found to have a different radius depending on what was around it.
