To determine the appropriate size of a steel I-beam for a 5,000-pound point load over a 20-foot span, you'll need to consider factors such as the beam's material properties and safety factors. Typically, a W8x10 or W10x12 I-beam might be suitable for this load, but it's crucial to perform detailed calculations or consult a structural engineer to ensure compliance with local building codes and safety requirements. Additionally, factors such as beam support conditions and deflection limits should be considered in the final design.
You will have to have an engineer spec that beam for you. You will save yourself time and money by cutting the span with a column.

To determine the appropriate beam size for spanning 16 feet under a 35 psf roof load, you would typically consult a span table or structural engineering guidelines. Generally, a glulam beam or a steel I-beam may be needed, with sizes varying based on factors like the beam material and specific load conditions. For a rough estimate, a glulam beam of about 3x12 or a steel I-beam around 8x10 inches could be suitable, but a structural engineer should be consulted for precise calculations and local code compliance.
For ceiling joists, the minimum dimension per the IBC is a 2 x 12 inch, with spacing dependent on the load. Ideally, these would be screwed to blocking between the joists.
What size steel I beam do I need to span a 32 feet garage with a floored storage above and no posts
That really depends upon the load you need to carry and the material that the beam is made of.
The size of the beam needed to span 8 meters depends on several factors, including the type of material (wood, steel, concrete), the load it will support (live load and dead load), and the beam's design (e.g., continuous, simply supported). For example, a steel I-beam may be smaller than a wooden beam for the same load. It's essential to consult structural engineering tables or a professional engineer for specific calculations and recommendations based on the project's requirements.

That always depends on what the beam will be carrying. You will need to consult a building contractor to size any beam correctly. IT ALSO DEPEND ON ITS MATERIAL &ALSO HOW MANY STOREY CONSTRUCTION REQUIRED ON THIS
That question cannot be answered without knowing the load on the beam.

Span/load beam questions really cannot be answered. You will need to have the plans looked at by a engineer. At the very least the lumber yard selling the beam may have an on-staff engineer to have a look at it.
That depends on what it is carrying. . .you definitely need to consult a structural engineer for this information, and having the original set of plans to show him will help. FYI. . .28 feet is a VERY long clear-span for any type of beam.
1 ft by 1.2 ft... verticaly 1.2ft
Use a steel beam.. That would be code.. steel w10x15 (50ksi) I beam.
