Depends on the material the I-beam is made out of. Steel? Is it a wood I-joist? And I-beams come in different "flavors" as regards the geometry and cross section of the web. Variables in a question make for a variable answer.
Wood? metal? Load? to many variables to answer that question.
For a supported ridge beam that will hold up 2 x 6 rafters a 2 x 8 will work.
It depend on what material the beam is manufactured from.
230 * 600 mm
That depends on many other factors. What is the beam material? Is the load a point load concentrated in one spot, or is it uniform across the total span? Specing beams is something that should be left up to a qualified person.
These calculations are not difficult, but you must know the load (including the floor weight) that will be carried. And the deflections that the appropriate building regulations allow.
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.
By the cooling load of the home only.
With a span of only 8" you can probably use a wood beam, but without a set of plans no one can accurately answer your question.
The midpoint of a triangle is the 3rd sides' size, divided by 2.
That question cannot be answered without knowing the load on the beam.
A DLH will work.
What size steel I beam do I need to span a 32 feet garage with a floored storage above and no posts
what is bed load particle size
That depends on many other factors. What is the beam material? Is the load a point load concentrated in one spot, or is it uniform across the total span? Specing beams is something that should be left up to a qualified person.
8 gauge will be sufficient with less than a half volt drop
by the size of the load they are connected to. a general lighting circuit in a home should be 500 sq feet. an appliance will have it's connected load on the name plate. all electrical components [ plugs, cord, wire, anything electricity flows through] must be DERATED 20 %. if your load is 30 amp 240, add 6 amp[20%]to the 30, for 36amp. the closest wire size is #8.
The size of the generator is based on the size of the load you want to supply. Size up the load in watts or amps along with what phase (single or three) and voltage that the load requires. These are needed to give a complete answer.
There are too many variables to consider for your application. You should consult a qualified engineer for this project.
You will also need to include the acceptable amount of deflection in your question.
