THIS IS A HEAT TRANSFER PROBLEM!
Determine F12 and F21 for the following configurations using the reciprocity theorem and other basic shape factor relations.
Part (b): the figure shown to the right (and below). Also, find specific values of F-2, F-1, and F-2 at θ=5 (all segments are infinitely deep into/out of the page).
Arc is a semicircle of radius r. The arc is a straight line of equal length, at an angle θ to the horizontal. Line lengths change as θ changes. Together, the two lines "make up" A2.
