It 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.
timber = wood dam = structure built to block/slow the flow of water so... timber dam is a wooden structure created to block or slow the flow of water.
A beam is a crossbar of a balance, a large piece of timber or iron, a horizontal timber of a building, or a ray or collection of rays of parallel light.
Yes, it is.

About 5metres(16') but would have to be stress graded timber.
That really cannot be answered without seeing your plans and design. Your lumber supplier may size it for you, though it will be overkill...
Solid timber is cut from a single piece of wood. Plywood is manufactured from several sheets of wood laminated together.
Laminated veneer lumber
Timber is the tree after it is cut down. Lumber is the wood after it has been cut to its desired purpose.
I think the laminate board is the strongest because I tested it and that's what I got.

you use laminated timbers for kitchen surfaces and building things it is very strong disadvantages of the timber it isn't very strong

Timber was in demand in the New World because of rapid development. Timber was needed for housing, rail roads, and bridges.
