a framing member (2x4 or similar), attached to a wall, upon which, sits the top (high end) of a "pitched" rafter.
Placement of the plate determines the pitch of the roof, hence the name.
---------------------------------------
It is more commonly called a ridge board, or if it is designed to transfer load, it is called a structural ridge.
Pitching plate iscolloquial, and not a common term in the US.
From AS 1684.4 Residential Timber Framing Code 2.6.4.1 Coupled roof Pitched roof construction with a roof slope not less than 10°, with ceiling joists and collar ties fixed to opposing common rafter pairs and a ridgeboard at the apex of the roof (see Figure 7.1). A coupled roof system may include some area where it is not possible to fix ceiling joists or collar ties to all rafters, e.g., hip ends or parts of T- or L-shaped house. 2.6.4.2 Non-coupled roof A pitched roof that is not a coupled roof and includes cathedral roofs and roofs constructed using ridge and intermediate beams.

Roofs may be functionally flat or "pitched". In building construction, roof pitch is a numerical measure of the steepness of a roof. A flat roof on the otherhand, is a roof which is almost level in contrast to the many types of sloped roofs. The slope of a roof is properly known as its pitch and flat roofs have up to approximately 10°. If you have a flat roof, there is probably a leak in it or there will be a need for a flat roof repairs in the future.
In construction, TGI stands for "Truss Girder I-beam." It refers to a type of engineered wood or steel beam that is designed in the shape of an "I" to provide strength and support for structural applications. TGI beams are commonly used in floor and roof framing due to their efficiency in load distribution and lightweight properties.
38 feet longIt is not possible to give a definite answer without more detail. The construction and type of roof will determine the load (weight) bearing on the beam, and factors such as wind load and earthquake load, and the way the roof bears on the beam (truss/point load/distributed load) will all affect the sizing.
The purpose of the double top plate in framing construction is to provide additional strength and stability to the structure by distributing the weight of the roof evenly and helping to prevent the walls from shifting or bowing over time.

The purpose of a ridgeboard in roof construction is to provide support and stability to the rafters at the peak of the roof, helping to distribute the weight of the roof evenly and prevent sagging or collapsing.
Flat roof construction has many disadvantages. However the main disadvantage is that there is nowhere for rainfall water to flow. It will settle on the roof causing dampness.
A hipped end in roof construction is a roof end plane that is inclined, instead of having a gable end.Some roof designs can have a hip at one end, and a gable at the other end.
There is a 16 foot circle with the pitching plate as the center point.
The purpose of a roof ledger board in building construction is to provide support and stability for the roof structure by connecting the rafters or trusses to the building's frame.

The price of roof construction blueprints is pretty reasonable, but it does vary where you buy it. The blueprint can be picked up for as low as $49.98.
The maximum span for 2x6 rafters in roof construction is typically around 9 feet.
Roof skip sheathing is used in construction to provide a solid base for the roof covering and to help distribute the weight of the roof evenly across the structure. It also helps to prevent the roof from sagging or warping over time.
The maximum span for 2x6 rafters in residential roof construction is typically around 9 feet.
