Answer: Find a suitable diameter for the shaft, if the maximum torque transmitted exceeds the mean by 30%. Note that if a unit of measurement is given, it's important to carry it all the way through your calculations. The value of $\nu$ is listed for many engineering materials - see for example the engineering toolbox. The radius – the distance from the circle's center or origin to the edge, one half the diameter. Asking for help, clarification, or responding to other answers. If you know the circumference, you can divide the circumference by pi and this will be your diameter (diameter = circumference / pi). The telescope maker's approximate formula for the radius of curvature of a mirror surface is s = r^2/2R, where r is half the mirror diameter, s is the radius of curvature of the surface (half the focal length), and R is the saggita (depth of the curve).
