We know that sin @ = h/l is the basic principle of working of sine bar.
Differentiating above equation,
.
. . cos @ . d@ = l.dh - h.dl
_________ l*l
d@ =tan@(dh/l - dl/l)This indicate that error is a function of tan @ and below 45 degree error is smaller which suddenly increases above 45 degree. because of this reason sine bar is preferred for measuring angle below 45

Question poised to me by contractor. What pitch is your roof My answer was that it rises at a 25 degree angle. What is the pitch in his terms?
If I remember right it should be between a 5 and 6 pitch. Between a 5/12 pitch and 6/12 pitch. If it was 27.5 degrees it would be a 6/12 pitch. Enter in "roof pitch" in the Google bar and several sites will come up where you can calculate pitch. The 12 means 12 inches. So that it would be aproximitely 6 inches rise to 12 inches of run. Hope this helps and I hope I remember my roof pitch angles. It has been a few years since I have done it.
