Rake moulding width {in terms of x and y} =
ecwa = (eave crown wall angle)
rsa = (roof slope angle)
ecw = (eave crown width)
(y) = ((cos((ecwa) (-) (rsa))) * (ecw))
(x) = sqrt(((y2) + ((ecw) * ((sin(ecwa))2))))
or in one expression {x}. . .
(x) = sqrt(((((cos((ecwa) (-) (rsa))) * (ecw))2) + ((ecw) * ((sin(ecwa))2)))).
The wall angle of this crown is. . .
a = (sin-1 (sin(ecawa)/x))
Good luck Pisáno!
