A quarter of transparent cylinder with index of refraction of n=5/3 is surrounded by a vacuum and is exposed? - index.of ls magazine.com
a beam of light parallel to the base material. What is the maximum amount of the output beam L incident beam is perpendicular to the base? Send your answer (to one decimal place) as a fraction of the cylinder radius R.

I do not understand the geometry that the level of "maximum" of importance.
I think that is the question: "When the quarter cylinder is positioned so that a beam of light to the entrance of the vertical planes parallel to the axis of the cylinder, but far enough (from the axis itself, and can the overall experience of inner reflection and thoughtful perhaps repeatedly), the left parallel to the axis of the other.
Furthermore, if the beam near the tree out of the curved surface is located instead.
Where is the line (the radius of the cylinder) between the two behaviors. "
If that is the question, then the answer is the radius at which the beam strikes the surface curves in the critical angle:

You certainly can, but the hardest part of the clip DE / magazines, like most retailers in the U.S. population that will find the extended version.
Normally, everyone wants to throw more, no less!
