PROBLEMS FOR CHAPTER 6
P6.1.
The common rafters on a particular structure have a 5-1/2
⬙
pitch
and a run of 13
⬘
-4
⬙
. Find the rise, length, plumb and level cut
angles for these rafters.
P6.2.
For common rafters having a rise of 8
⬘
-5
⬙
and a run of 15
⬘
-3
⬙
,
determine the pitch (in inches and degrees), length, plumb and
level cut angles.
P6.3.
Common rafters on a shed roof have a 4
⬙
pitch and a rise of 3
⬘
-8
⬙
.
Calculate the run, length, plumb and level cut angles for these
rafters.
P6.4.
A conventional roof has two sections containing common rafters
with a 6
⬙
pitch and 15
⬘
-9
⬙
run. For these common rafters, find the
pitch (in degrees), length, plumb and level cut angles. Also
determine the length; plumb, level, and cheek cut angles for hip
and valley rafters used to join the two roof sections.
P6.5.
For the roof of problem P6.4, calculate all hip jack lengths for a
spacing of 16
⬙
o.c. . Repeat for 24
⬙
o.c. .
P6.6.
A conventional roof has a 12
⬙
pitch and an 8
⬘
run. Calculate the
pitch (in inches), length, plumb and level cut angles for all
hip/valley rafters used on this roof.
P6.7.
For the roof of problem P6.6, find the lengths of all jacks at a
spacing of 24
⬙
o.c. .
P6.8.
An irregular roof contains one section whose common rafters have
a 5
⬙
pitch and a run of 11
⬘
-8
⬙
, and another section having a pitch of
6-1/2
⬙
. Find the length, plumb, level and cheek cut angles for all
regular and irregular jacks to be used on this roof if their spacing is
24
⬙
o.c. throughout.
P6.9.
A rake wall with no base has a 4
⬘
-6
⬙
rise and a 14
⬘
-0
⬙
run. Find the
lengths of all rake-wall studs at 24
⬙
o.c., as well as the cheek angle
to be cut at the top of each stud.
P6.10.
A rake wall with an 8
⬘
-4
⬙
base has a 5-1/2
⬙
pitch and a run of
9
⬘
-10
⬙
. Determine the rake-wall stud lengths at 16
⬙
o.c., and the
cheek cut angle for these studs.
