Solution :
Given :
Span of the roof = 48 feet
Length of the rafter = 30 feet (including the 4 feet overhung)
So, for the 30 feet long rafter, 26 feet will be rafter length from the high point of the roof to the edge of the roof and 4 feet will be the roof overhung.
Therefore, the horizontal span per rafter is

= 24 feet
a). So the rise of the roof is
= 10 feet
b). Pinch of the roof is 


c). The percent of the roof used as overhung is


= 13.33 %
12 + 26 + 125 = 163
163 + 0.056(163) = 163 + 9.13 = 172.13
The answer is a <span>42.857% chance which is 3/8
