AG Module 4 Ceiling Joists and Roof Framing

Which of the following building components keeps opposite walls from spreading apart?

• Trimmer studs

• rafters

• ceiling joists

• purling

To transfer roof loads to the foundation, ceiling joists are usually installed

• on a double top plate

• between pairs of wall studs

• directly over wall studs

• with metal anchor plates

When ceiling joists must be overlapped above a loadbearing partition, the overlap must be at least

• 3"

• 6"

• 12"

• 18"

A shed dormer is typically used on a house built in the

• Federal style

• duplex style

• cape cod style

• ranch style

A board nailed to the tails of the rafters to provide a nailing surfaces for the fascia is the

• barge board

• false fascia

• lookout

the type of cut that is made to a rafter so it will rest squarely on the top plate is the

• notch

• bird's mouth

• sill cut

• joist cut

When laying out rafters, the distance between the last 2 may be less than 24", but NOT more than

• 16"

• 18"

• 22"

• 24"

In order to determine the correct length for a common rafter, it is necessary to

• subtract the width of the bird's mouth

• subtract half the thickness of the rafter

• subtract half the thickness of the ridgeboard

• add half the thickness of the ridgeboard

When making the bird's mouth cut, its depth should not exceed

• one-third the rafter's width

• the rafter's thickness

• one-fourth the rafter's thickness

• the depth of the top plate

Local fire codes must be consulted when framing an opening around a chimney to establish

• correct pitch

• rafter spacing

• proper clearance

• insulation requirements
