You still need to indicate the pitch, the roof sheathing, and the shingle weight.
Usually, a load bearing wall will be perpendicular to the roof ridge.
All exterior walls in a home are load bearing. The exterior walls on the gable end of your house do not bear much load, but the walls that the hip of the roof bear on carry your roof and ceiling joints. Interior walls are another story. Usually in a smaller one story home there is a wall that runs the midspan of the house that is load bearing for your roof and ceiling joints.

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.

That is not a simple anwer. It depends on the roof design and how many, and where the load points are, and the material of the beam(wood, metal, composite). See a structural engineer.

About 5metres(16') but would have to be stress graded timber.
Support the load whatever it is, roof, second floor, generally by putting a temporary beam under the joist inside of the existing wall, tear the wall out and put in a beam to carry the load. How big the beam needs to be depends on what the load is and how long the span is. Support the beam on each end and remove the temporary beam. These are the general steps, each project is going to be slightly different and has to be figured on it's own.
It depends on the roof load and the actual clear span. Off hand, I would guess htat you haven't given this much thought. A rule of thumb for a steel truss is one inch per foot of span or in your case 40 inches. If you want to use a steel I-beam, you can get that from a good municipal library from the steel beam institute, but you are going to need a crane to place it. Dieter in Cincinnati
Live load Both are the same Live load is all the live loads which can be consider as variable load. Roof live load This is limited to few categories. man who climbed on to the roof can be consider as roof live load.

Your question cannot be answered as it depends on what the beams load is... porch roof support vs a beam which will support a second story living area and a roof.
