Formulae. 1  Eclipsing binary: diameter = speed Ã time of eclipse. 2  Size from luminosity: star's radius/Sun's radius = (Sun's temperature/star's temperature)2 Sqrt[star's luminosity/Sun's luminosity].
MOA is a mathmatical concept that most firearm scopes incorporate. Minute of Angle (MOA) is critical to sighting in your scope. MOA mathematical concepts were used to develop the AccuScope scope sighting reference tool. The only MOA information needed to use AccuScope is your scope's MOA number.
In the third the â-â means bias construction. A âBâ would mean bias-belted.Next is rim diameter, in inches: 17 in the second photo, 18 in the third. The âM/Câ means the tire was designed for motorcycles. Motorcycle Industry Council Tire Guide9 The next set of characters indicate load index and speed index. The â69â and â62â indicate the maximum load the tire can carry (see Load Index Rating chart below) at the speed indicated by the speed indexes â(W)â and âH,â respectively (see Speed Index chart on the next page). In the chart, note that the W in parentheses has a different rating than a W without parentheses.
